Travelling by air with an Emotional Support Animal requires careful planning because there is no single worldwide ESA airline rule. Some airlines allow smaller dogs or cats in the cabin under their ordinary animal policy, while others accept only trained assistance dogs or do not carry animals in the cabin at all. The rules can change according to the operating airline, aircraft, route, destination, animal species, combined animal-and-carrier weight and available cabin spaces.
ESA registration, an identification card or a medical support letter can help explain why an animal is important to its handler, but these documents do not automatically create a right to cabin travel. Every flight segment must be confirmed directly with the operating airline before a non-refundable ticket is purchased. Travellers must also meet the animal-entry requirements of every destination and transit country.
Use the regional guides below to identify possible airlines and the questions that must be answered before booking. Airline policies and government entry rules can change without notice, so written confirmation for the complete outward and return itinerary is essential.

FLYING TOGETHER WITH EMOTIONAL SUPPORT ANIMALS
Which European airlines allow an emotional support animal in the cabin, and what must travellers check before booking? For someone who relies on an emotional support animal (ESA), the most important flight question is simple: can the animal stay with them in the cabin? Across Europe, many airlines offer that option for a small dog or cat. The difficulty is that most airlines book an ESA under their ordinary animal travel rules, with a carrier, weight limit and fee. That distinction matters. An ESA provides valuable emotional support, but airlines generally distinguish it from a trained assistance dog that performs specific tasks for a disabled person. A medical letter or ESA registration does not, by itself, give an animal the cabin access offered to a recognised assistance dog. LOT, Iberia, Lufthansa and airBaltic each make this distinction in their published policies. (LOT.com)
Airlines offering cabin travel for smaller ESAs
The following airlines publish cabin travel options that may work for an ESA when the animal meets the airline’s ordinary animal travel conditions. The weight shown is generally the combined weight of the animal and its carrier. Aegean Airlines A dog or cat can travel in a carrier, subject to available animal places on the flight. (en.aegeanair.com). Weight limit is 8 kg. Air France and KLM Both offer cabin travel for small dogs and cats. Confirm the operating airline’s rules on each flight. (Air France, Russia). Weight limit is 8 kg. Austrian Airlines Small dogs and cats can travel in a soft carrier. (Austrian Airlines). Weight limit is 8 kg. Brussels Airlines Dogs and cats can travel in the cabin in an approved bag. (Brussels Airlines). Weight limit is 8 kg. Finnair Its cabin policy includes small dogs and cats and, under specific conditions, some other species. (Finnair). Weight limit is 8 kg. LOT Polish Airlines Dogs, cats and ferrets are eligible for cabin travel. LOT says an ESA without assistance-animal training travels under its paid animal rules. (LOT.com). Weight limit is 8 kg. Lufthansa and SWISS Small dogs and cats may travel in the cabin. Both distinguish ESAs from trained assistance dogs. (Lufthansa). Weight limit is 8 kg. SAS Scandinavian Airlines Small dogs and cats may travel in a carrier beneath the seat, subject to route restrictions. (SAS). Weight limit is 8 kg. TAP Air Portugal Dogs and cats may travel in the cabin in a carrier that meets TAP’s size rules. (flytap.com). Weight limit is 8 kg. airBaltic Dogs and cats may travel under its paid animal policy. airBaltic explicitly says an ESA cannot travel as an assistance animal in the cabin, but an emotional support dog or cat can travel there under its ordinary animal rules. Its published cabin charge is €70 per carrier, per direction, on airBaltic flights. (Cabin & Cargo Rules). Weight limit is 8 kg. These are options for cabin carriage, not promises that a particular ESA will be accepted on every flight. Airlines limit the number of animals aboard, and carrier dimensions, age, breed, aircraft and destination can all affect a booking.
More European airlines to consider
Several carriers beyond the original list also publish cabin animal options:
Iberia accepts eligible small animals in the cabin, subject to route and availability. It states explicitly that emotional support dogs follow its ordinary animal acceptance conditions. (Iberia Spain)
Vueling permits eligible animals in a soft carrier weighing up to 10 kg including the animal. It does not carry animals in the aircraft hold, so it is unsuitable if an ESA exceeds its cabin limit. (Vueling help)
Transavia permits cabin travel up to 8 kg including the carrier. Its policy restricts short-nosed animals to cabin travel rather than the hold. (Transavia)
Turkish Airlines permits eligible animals in the cabin up to 8 kg including the carrier. Its seat rules mention emotional support dogs, but travellers should confirm the animal’s booking category and conditions directly with the airline. (Turkish Airlines ®)
Pegasus Airlines offers paid cabin carriage for eligible animals up to 8 kg including the carrier. Its hold options vary by route. (Pegasus Airlines)
Air Europa publishes cabin conditions for eligible dogs and cats; travellers should check the combined weight and breed rules for their route. (Air Europa United Kingdom
ITA Airways permits dogs and cats in the cabin up to 12 kg including carrier and food on Italian domestic flights, and 8 kg on other flights. It also advertises a separate service for larger dogs on selected domestic flights, which requires its own booking and conditions. (ITA Airways)
ITA’s domestic allowance and Vueling’s 10 kg limit are particularly useful to check when an ESA narrowly exceeds the 8 kg limit common among other carriers. The carrier counts towards the limit, so weighing the animal alone can give a misleading answer.
The UK exception can change the whole journey
A flight that accepts an ESA in the cabin elsewhere in Europe may be unable to bring that animal into Great Britain in the same way. UK government guidance says animals arriving by air generally must travel as cargo, except on a qualifying private charter or when travelling as a guide or assistance dog. Separate arrangements apply to recognised assistance dogs. (GOV.UK) This is especially important for a return trip. An airline’s general cabin policy does not override entry rules at the destination. Iberia, for example, publishes specific restrictions on cabin animals on UK routes and directs travellers needing animal transport to cargo arrangements. (Iberia Spain) Other destinations can impose their own animal entry and airline carriage conditions. Travellers should check the rules for every country and every flight segment, including connections.
When an airline will not carry an ESA under its animal policy
Some familiar European airlines are poor choices for travellers hoping to bring an ESA aboard under ordinary animal travel rules. easyJet says emotional support dogs and other animals are not accepted, apart from qualifying assistance dogs. Ryanair says it does not carry animals except guide and assistance dogs on eligible routes. Wizz Air states that it does not accept emotional support animals. (easyjet.com) These policies reinforce why the words used when booking matter. An airline’s acceptance of assistance dogs does not mean it accepts ESAs on the same terms.
What to confirm before paying for flights
The most ESA-friendly itinerary is one for which the traveller has written confirmation that the animal can travel on every leg. Before purchasing a non-refundable fare, ask the operating airline to confirm:
The animal’s booking category, permitted species and combined animal-and-carrier weight.
The exact carrier dimensions and whether it must remain beneath the seat throughout the flight.
Space for an animal in the cabin on each flight, including any codeshare or connection.
All charges, documents, minimum-age rules and breed restrictions.
The destination’s entry rules and the arrangements for the return journey.
Short-nosed breeds need particular care: some airlines restrict their travel in the hold because of breathing and heat-related risks. LOT, for example, prohibits these breeds in the baggage hold while allowing them in the cabin if they meet its cabin conditions. (LOT.com) For an ESA owner, a useful airline is one that can confirm the animal will be beside them on the actual route booked. Europe offers a substantial choice for smaller animals, but the right flight depends on the animal’s size, the operating carrier and the rules at the destination. Confirming all three before booking can prevent the most distressing discovery: finding out at check-in that an animal essential to the journey cannot board.
FLYING WITH EMOTIONAL SUPPORT ANIMALS IN THE USA
Which US airlines allow an ESA in the cabin, and what do travellers need to arrange before they fly? For someone who depends on an emotional support animal, choosing a flight means more than finding the right departure time. The central question is whether the animal can remain close throughout the journey. Many US airlines allow small dogs and cats in the cabin. An emotional support animal usually travels under the airline’s ordinary animal policy, however, with a fee and a carrier that fits beneath the seat. Its ESA status alone does not provide the cabin access granted to a trained service dog. American, Delta and United state this distinction in their current guidance. (aa.com) That does not lessen the support an ESA provides. It does mean that travellers need to choose a flight their animal can actually take, then reserve the animal’s place before departure.
Why ESAs and service dogs have different flight rules
Under US Department of Transportation rules, a service animal is a dog individually trained to perform work or tasks for a person with a disability. This includes a qualifying psychiatric service dog. Emotional support animals are a separate category and are not treated as service animals under the federal air travel rule. (US Department of Transportation) The practical difference can be considerable. A qualifying trained service dog may accompany its handler in the cabin under service-animal rules, subject to the airline’s documentation and safety requirements. An ESA must meet the airline’s conditions for an animal travelling in a carrier if that is the route by which the airline accepts it. An ESA letter, registration or identification card does not change those airline conditions. (US Department of Transportation)
US airlines with cabin options for ESAs
These airlines publish cabin animal options that may accommodate an ESA if it meets the rules for the animal’s species, carrier and route. This is a guide to available options, not a ranking or a guarantee of acceptance on every flight. American Airlines Allows an eligible dog or cat in an under-seat carrier on permitted routes for a fee. American explicitly says ESAs travel under its ordinary animal rules. (aa.com) Delta Air Lines Allows eligible small dogs and cats in the cabin for a one-way fee; household birds are also accepted on certain domestic flights. Delta does not recognise ESAs as service animals. (Delta Air Lines) United Airlines Allows eligible cats and dogs in cabin carriers and explicitly states that emotional support cats and dogs must follow its ordinary animal rules. (united.com) Southwest Airlines Accepts eligible small dogs and cats in carriers on domestic flights. It says ESAs may qualify under this policy. Cabin spaces are limited. (Southwest Airlines) Alaska Airlines and Hawaiian Airlines Publish options for smaller animals in under-seat carriers, with baggage-compartment options for some larger animals and routes. Hawaiian says emotional support and comfort animals may travel under its ordinary animal rules when eligible. (Alaska Airlines and Hawaiian Airlines) JetBlue Allows small dogs and cats in approved under-seat carriers on eligible flights. Its published cabin animal fee is $150; travellers should check the fare, aircraft and route before booking. (jetblue.com) Frontier Airlines Offers cabin travel for eligible animals but says ESAs are not accepted as service animals. Anyone travelling with an ESA should book it under the ordinary cabin animal policy and confirm eligibility first. Frontier does not transport animals in the cargo hold. (Frontier Airlines) Spirit Airlines Says ESAs can travel in the cabin for an additional charge if they meet its animal-in-cabin conditions. Spirit does not accept animals as checked baggage or cargo. (customersupport.spirit.com) Allegiant Air Accepts eligible dogs and cats in under-seat carriers on flights within the contiguous 48 states, subject to its conditions and a per-segment fee. (allegiantair.com) Sun Country Airlines Accepts small dogs and cats in the cabin on selected flights within the contiguous 48 states. It lists a $75 fee per direction when arranged in advance. (suncountry.com) Breeze Airways Accepts eligible small dogs and cats in the cabin on domestic flights, subject to limits on the number of animals aboard and seating restrictions. (media.flybreeze.com) Avelo Airlines Accepts eligible small cats, dogs, rabbits and birds in under-seat carriers on domestic flights. Its policy limits the number of animal carriers per flight. (aveloair.com) For an ESA owner, the distinction in airline wording is crucial. When Frontier says it does not accept an “emotional support animal,” it is referring to ESA status as a special travel category; it separately offers ordinary cabin animal travel for eligible animals. The animal must be booked under the category the airline will actually accept. (Frontier Airlines)
Size can decide the journey
The under-seat carrier is the main obstacle for many ESA travellers. An animal must be able to fit comfortably in a carrier that complies with the operating airline’s dimensions. On airlines requiring the carrier to remain beneath the seat, buying an additional passenger seat does not automatically remove that requirement. American’s policy, for example, requires cabin animals to stay in their carriers under the seat. (aa.com) Options for a larger ESA require careful research. Alaska and Hawaiian publish baggage-compartment transport options on eligible services, while Frontier and Spirit say they do not offer ordinary animal transport in the hold. Availability can also depend on aircraft, weather, destination and the animal’s breed. (Alaska Airlines and Hawaiian Airlines) A larger animal’s ESA designation does not create an exception to cabin carrier rules. If remaining together in the cabin is essential, confirm that the animal fits the airline’s actual carrier requirement before buying the ticket.
Domestic routes are simpler than international ones
An airline that accepts an ESA in a carrier on a domestic flight may restrict animals on an international route. JetBlue says it accepts small dogs and cats on most international flights, while stressing that each destination has its own entry requirements. Southwest’s cabin animal policy applies to domestic flights. Sun Country’s published option is limited to selected flights within the contiguous United States. (jetblue.com) Connections need the same attention. A ticket may carry one airline’s name while another operates a flight. If the journey involves two airlines, each operating carrier must confirm the animal’s place. Entry requirements, vaccination records and other documents must also be checked for the destination and the return journey.
Book the animal’s place before the flight
Airlines restrict how many animals can travel in a cabin. Southwest’s published conditions, for example, allow it to limit flights to six animal carriers, with places accepted on a first-come basis. A passenger ticket alone does not reserve a place for an ESA. (southwest.com) Before paying for flights, travellers should obtain confirmation of:
Species and route: whether the animal is accepted on every flight, including connections.
Carrier fit: the permitted dimensions and whether the animal can stand, turn and lie down as required.
Cabin availability: a confirmed animal reservation, rather than a general statement that the airline accepts animals.
Total cost: fees for each direction or flight segment.
Documents: the airline’s requirements and the rules of every destination.
It is also wise to keep the airline’s confirmation with the travel documents. Policies can change, and an answer about a general route may not account for a particular operating aircraft or connection.
The choice that matters most
US travellers have a wide range of airlines offering cabin carriage for smaller ESAs. But the most suitable airline is the one that confirms this animal, in this carrier, on this complete itinerary. An ESA can be indispensable to the person travelling with it. Clear booking rules allow that relationship to be planned for properly: check the animal’s size and route, reserve its cabin place, and make sure every airline involved has accepted the arrangement before the day of travel.
FLYING WITH EMOTIONAL SUPPORT ANIMALS BEYOND THE USA AND EU
An airline guide to cabin travel in Canada, Latin America, the UK, Switzerland, Türkiye, the Middle East, Asia and Australia The airline’s home country is only the beginning of an emotional support animal (ESA) travel plan. A carrier may allow an ESA in the cabin on one route, require the same animal to stay inside an under-seat carrier on another, or offer no cabin option at all. This guide covers airlines based outside the United States and European Union. It includes carriers that recognise emotional support animals as a specific travel category as well as carriers that may take a smaller ESA under their ordinary animal travel rules. Those are different booking arrangements. Before buying a ticket, travellers need the operating airline to confirm which one applies to their animal and route.
Canada
Air Canada
Air Canada publishes a dedicated process for travelling with an emotional support dog. The dog must be able to travel safely and comfortably in an approved carrier under the seat. Air Canada also requires documentation, including a form completed by a licensed medical or mental health professional who is treating the passenger. It does not accept other species under its emotional support animal category. Travellers should contact its Accessibility Services team before booking to confirm the requirements for their particular flight. (aircanada.com)
Porter Airlines
Porter explicitly accepts eligible emotional support dogs in the cabin. On flights within Canada, the dog must remain inside an approved carrier throughout the journey. Porter requires supporting documentation from a licensed medical or mental health professional, dated within one year of the flight, and asks travellers to arrange assessment through its Disability Assistance Desk. The rules change on flights to the United States: Porter says an emotional support dog must travel under its ordinary cabin animal policy, subject to space and the applicable fee. Porter does not accept cats as emotional support animals, although travellers can separately check its ordinary cabin policy for a cat. (Porter Airlines)
WestJet
WestJet no longer accepts emotional support animals under an ESA cabin category. An eligible small dog or cat may still be booked under its ordinary cabin animal rules; a larger animal may need a baggage-compartment arrangement where the route permits one. Travellers should obtain confirmation for both directions before booking. (WestJet)
Mexico, Central America and South America
Aeroméxico
Aeroméxico’s published animal travel information lists emotional support dogs and cats as a distinct cabin category, with a stated limit of 12 kg, alongside an ordinary under-seat animal option of 9 kg including the carrier. That makes its policy especially relevant to travellers whose animal exceeds the usual small-carrier allowance. Acceptance still depends on the route, documentation, animal and space available; travellers should confirm how the ESA category applies to the exact flights they intend to take. (Aeroméxico)
Avianca
Avianca has a specific process for emotional support dogs. It permits one eligible dog in the cabin in a flexible carrier placed beneath the seat, subject to documentation, availability and behaviour requirements. Its current guidance says cats are not accepted under the emotional support category. The dog must remain in its carrier during the flight. Avianca also warns that an emotional support dog cannot travel in the cabin in Business Class on its Boeing 787 aircraft. Travellers connecting to a partner airline must check that airline’s rules separately. (Help Center avianca)
LATAM Airlines
LATAM recognises emotional support animals only on specified routes. Its published guidance lists emotional support dogs on certain flights involving Argentina, Mexico and Colombia, and on domestic flights within Colombia. It lists emotional support cats on flights to or from Colombia and on Colombian domestic flights; cats must remain in an approved carrier beneath the seat. For other routes, LATAM directs travellers to its ordinary animal transport options, if the animal qualifies. It asks passengers to request emotional support dog transport in advance and submit its form and supporting documents. A LATAM booking therefore needs a route-by-route check: acceptance on one journey does not establish acceptance on another. (LATAM Airlines)
Copa Airlines
Copa publishes separate guidance concerning emotional support dogs, service dogs and animals travelling in cabin carriers. Its policies have been updated over time, so travellers should ask Copa to confirm the current ESA requirements, documentation, seating arrangement and acceptance on every flight in the itinerary. Copa’s lounge rules also distinguish emotional support dogs from ordinary cabin animals. (copaair.com)
United Kingdom and Switzerland
British Airways
British Airways does not accept emotional support dogs in the cabin on flights it operates. It says an emotional support dog must travel under its ordinary animal transport arrangements, while qualifying trained assistance dogs are assessed under separate rules. This makes British Airways unsuitable when an ESA must remain beside its handler throughout the flight. (British Airways)
Virgin Atlantic
Virgin Atlantic’s conditions distinguish assistance dogs accompanying eligible passengers from animals travelling under its other transport arrangements. Its published cabin provision is for accepted assistance dogs. Travellers with an ESA should contact Virgin Atlantic before booking to establish whether the animal can travel on the intended route and how it would be transported. (virginatlantic.com)
SWISS
SWISS allows eligible small dogs and cats in the cabin when the animal and soft carrier together weigh no more than 8 kg. It explicitly says emotional support dogs do not count as assistance dogs. A smaller ESA may therefore be able to accompany its handler inside a carrier under SWISS’s ordinary animal rules, subject to reservation, aircraft and route restrictions. (SWISS)
Türkiye and the Middle East
Turkish Airlines
Turkish Airlines allows eligible small animals in the cabin when animal and carrier together weigh no more than 8 kg and the carrier meets its dimensions. Its special assistance page also refers to advance reservations for emotional support dogs. Because the airline discusses ESAs and ordinary cabin animals in different parts of its guidance, travellers should ask Turkish Airlines to confirm which booking category and conditions apply to their specific route. An ESA mention on a webpage should not be taken as approval for an animal to travel outside a carrier. (Turkish Airlines ®)
Etihad Airways
Etihad offers a cabin option for eligible cats and dogs weighing up to 8 kg including the carrier. Animals must be at least 16 weeks old, and Etihad says this option is available in Economy and Business on eligible Etihad-operated flights. It does not treat emotional support, comfort or companion dogs as trained service dogs. Etihad asks travellers to submit its animal booking form at least seven days before travel, with required documents sent by its stated deadline. Its policy also warns that a connection operated by another airline can prevent carriage of the animal under the Etihad booking. (etihad.com)
Emirates
Emirates says emotional support and therapy animals are not treated as service animals. Its general policy does not permit dogs or cats in the passenger cabin under ordinary animal rules; animals must instead travel under its applicable transport arrangements. Its limited cabin exception for falcons does not create a cabin option for an ESA dog or cat. (Emirates
Qatar Airways
Qatar Airways states that emotional support dogs are not accepted in the cabin as service dogs. Its general animal policy carries eligible dogs, cats and birds as checked baggage or through other approved arrangements, while its cabin animal exception concerns falcons. Travellers should use Qatar Airways’ current animal guidance rather than older documents that describe different ESA rules. (Qatar Airways)
Asia and the Pacific
ANA
Japan’s ANA has an unusually specific, route-dependent policy. It says emotional support dogs may travel in the cabin on eligible flights to or from Mexico. That permission does not extend across its entire network. ANA says a dog on an ineligible route, including a connection beyond an eligible destination, may have to travel in the cargo compartment under its animal rules. Travellers must contact ANA’s Disability Desk and provide the documents required for the route. (ANA)
Air India
Air India’s current animal travel FAQ states that emotional support animals are not allowed on its flights, even though it separately offers ordinary cabin carriage for eligible dogs and cats on some routes. That wording needs direct clarification from Air India before a traveller attempts to book an animal that is also an ESA. Its animal restrictions also vary substantially by destination, including the UK, Australia, Canada and the USA. (Air India)
Virgin Australia
Virgin Australia now offers Pets in Cabin on selected domestic flights, including services involving Melbourne, Adelaide, the Gold Coast and the Sunshine Coast. An eligible small dog or cat must weigh no more than 8 kg together with its carrier and remain in the closed carrier beneath the seat throughout the flight. These are specific services and seats, so travellers must check that their chosen flight participates in the programme. The programme is an ordinary cabin animal option; travellers should not assume it confers assistance-animal status on an ESA. (virginaustralia.com)
Qantas
Qantas says an emotional support dog that has not been trained to perform tasks alleviating a person’s disability is not a service dog under its policy. An animal not approved for cabin travel as a service dog may be eligible to travel through Qantas Freight instead. Qantas is therefore unsuitable for an ESA traveller who needs an ordinary cabin option beside them. (Qantas IN)
Air New Zealand
Air New Zealand’s cabin guidance centres on eligible service dogs. Its ordinary domestic animal travel arrangements involve checked transport rather than a general cabin option for ESA dogs and cats. Travellers who need an ESA with them in the cabin should confirm any possible exception directly with the airline before making a reservation. (airnewzealand.co.nz)
The return journey matters as much as the outward flight
Cabin approval from an airline does not override a country’s entry rules. Great Britain generally requires animals arriving by air to travel as cargo, with separate provisions for qualifying guide and assistance dogs and limited other exceptions. An ESA may therefore be allowed beside its handler on an outbound flight yet be unable to return to Great Britain in the cabin. (www.gov.uk) The safest booking sequence is to confirm the animal’s category, cabin place and carrier requirements on every operated flight, then check entry requirements for each destination and the return. For ESA travellers, the decisive question is specific: Will this animal be accepted with me in the cabin on this entire journey, and under what conditions?
Before paying for any flight
Ask the operating airline to confirm the animal’s accepted booking category.
Confirm the permitted species, breed, age and combined animal-and-carrier weight.
Obtain the exact carrier dimensions and rules for keeping it beneath the seat.
Reserve an animal place on every flight, including connections and codeshares.
Confirm all charges and required veterinary, import and airline documents.
Check entry and transit rules for every country on both the outward and return journeys.
Keep the airline’s written confirmation with the travel documents.
