IATA Issued New Guidelines for In-Cabin Pet Transport: What to Check Before Traveling
The International Air Transport Association published new operational guidelines for airlines regarding in-cabin pet transport on July 15, 2026. For passengers, this does not mean automatic permission to take any animal on any flight, but it may make the rules clearer: from the moment of booking to passing customs or veterinary control after arrival.
The topic seems niche only at first glance. Traveling with pets has become a noticeable part of the aviation market: people more often plan long trips, relocations, remote work abroad, and vacations together with a dog or cat. At the same time, pet travel often creates the most unpredictability: one airline allows an animal in the cabin, another requires processing through the cargo department, and a third accepts only certain breeds or limits the number of animals per flight.
The new IATA document is important because it describes not a single separate norm, but the entire journey of a passenger with an animal. The guidelines cover the stages of booking, preliminary preparation, registration, aviation control, boarding, stay on board, transfers, disembarkation, arrival, and actions during delays or route changes. For tourists, this is a practical signal: a successful flight with an animal begins not at the airport, but before buying the ticket.
What Exactly IATA Published
IATA presented the first edition of the Operational Guidelines for In-Cabin Pet Transport. This is an operational document for airlines, prepared with the participation of specialized IATA groups working with live animals, ground handling, passenger processes, cargo operations, and aviation accessibility. Its goal is to help carriers make in-cabin pet transport more predictable, safe, and consistent.
In the press release, IATA emphasizes that passengers need a clear understanding of what will happen at each stage of the route. According to the Global Passenger Survey 2025, approximately a quarter of respondents had already traveled or considered traveling with a pet. Among those who had such an interest, 41% cited uncertainty regarding the animal's fitness for transport as a problem, 36% were unsure about airline policies, and 34% about the process itself.
These figures explain well why the topic has gone beyond separate rules for pet owners. Passenger uncertainty turns into longer calls to call centers, arguments at registration, risk of boarding denial, delays at the gate, and difficult situations during transfers. For airlines, a single logic of the process is a matter of operational discipline, and for tourists, it is a way to avoid a costly mistake on the day of departure.
Are These New Mandatory Rules or Recommendations?
The most important clarification: the IATA document is not a universal law and does not by itself cancel the rules of a specific airline, country, or airport. The guidelines explicitly emphasize that the transport of cats and dogs in the cabin depends on the airline's policy and must comply with the container requirements of the IATA Live Animals Regulations. Other categories of animals may be accepted only if they meet the carrier's requirements and applicable rules.
That is, a passenger should not read the news as permission to buy a ticket and arrive at the airport with an animal without prior agreement. On the contrary, the main point of the document is to make the process more transparent before the trip. Airlines are recommended to clearly show which animals are allowed, what restrictions apply by species, size, age, health status, breed, container, destination, and transit rules.
For travelers, this means a simple but strict logic: first, check the rules of the carrier, the country of departure, the country of transit, and the country of arrival, and only then book the route. Passengers with multiple airlines on one route or with separate tickets must be especially careful. If one segment accepts an animal in the cabin, it does not guarantee that another carrier will do the same.
Booking: What to Check Before Buying a Ticket
One of the key blocks of recommendations concerns booking. IATA advises airlines to explain the requirements for reserving a space for an animal to passengers in advance. The document provides a guideline: usually, such a request must be mandatory at least 48-72 hours before departure. This is important because the number of animals in the cabin may be limited, and some types of aircraft have different capabilities for container placement.
Passengers should not limit themselves to searching for the cheapest fare on an aggregator site. IATA specifically draws attention to the fact that not all travel agencies, meta-search engines, or third-party platforms support booking the pet in cabin service. If the service does not provide the option to add an animal to the booking, it is necessary to contact the airline directly and obtain confirmation before payment or at least before the end of the free cancellation period.
In booking systems, a special code PETC is used for animals in the cabin. A passenger does not necessarily need to know the technical details of aviation messages, but it is useful to check that the animal is actually entered into the booking, not just mentioned in correspondence. For international routes, it is also necessary to prepare data about the animal, container, medical documents, vaccinations, permits, and possible airline forms in advance.
Container, Documents, and Animal Condition
The most common cause of problems on the day of departure is non-compliance of the container or documents. IATA guidelines state that the container must meet the carrier's standards and IATA LAR CR1 requirements: the animal must be able to stand, sit, lie in a natural position, and turn normally inside. If the bag is too small, poorly ventilated, does not close securely, or does not fit in the allowed storage area, the airline may refuse transport.
IATA also advises carriers to prepare registration staff to check not only documents but also the condition of the animal. If the animal looks sick, excessively lethargic, aggressive, severely frightened, or demonstrates unacceptable behavior, boarding may be prohibited. This is not a formality: in the aircraft cabin, the animal is near other passengers, crew, and security systems, so the airline must consider the animal's welfare and the comfort of people on board.
The document also reminds about sedative drugs. IATA does not encourage the use of sedatives or tranquilizers for animals during transport unless prescribed by a veterinarian. If a drug was used, the airline may require corresponding veterinary confirmation. Passengers should not experiment before the flight: the animal's reaction at altitude, under stress, and in a limited space can be unpredictable.
At the Airport and On Board: Where the Most Misunderstandings Arise
After arriving at the airport, the passenger must be ready for several checks. At registration, the entire route, documents, vaccinations, certificates, permits, owner's contact details, and container parameters may be reviewed. During aviation control in different countries, animals may be inspected differently: in some places, a visual check is sufficient, in some places, the container is scanned separately, and the animal must be temporarily removed according to security rules.
At boarding, staff must ensure that the container is safe, ventilated, closed, and can be placed in the allowed area. In most standard scenarios, this refers to the space under the seat in front, but this depends on the aircraft, cabin, seat, and carrier policy. If placement under the seat is impossible, the airline must determine another safe option that does not harm the animal and does not interfere with evacuation.
On board, the main rule remains simple: the animal must remain in the container throughout the flight, including during taxiing, takeoff, landing, and turbulence. The passenger must not let it into the aisle, on the seat, or into the crew area. IATA also advises airlines to train crew to react to conflicts related to allergies, phobias, hygiene, or the concern of other passengers.
Transfers, Overnight Stays, and Arrival
For tourists with animals, routes with transfers are the riskiest. IATA explicitly states that areas for walking or relieving the needs of animals depend on the specific airport: in some places they exist after security control, in some only before registration, and in some airports such areas may not exist at all. Therefore, a long transfer is not always more convenient than a short one: it is necessary to look not only at the time but also at the available infrastructure.
If the route goes through large hubs, passengers should check the terminal layout and movement plan in advance. For example, for general preparation for the route, you can view the pages of London Heathrow Airport (LHR), New York JFK Airport, or Rome Fiumicino Airport (FCO), if these hubs are part of the journey. For overnight connections or forced delays, it is useful to separately check hotels near the airport, specifically near London Heathrow, but accommodation conditions with animals must be confirmed directly with the hotel.
After arrival, the issue does not end at the aircraft doors. IATA guidelines describe possible requirements for customs, veterinary, or border control: the animal may have to remain in the container until checked, and the passenger may need original documents, the animal's passport, vaccinations, medical certificates, import permits, or microchip confirmation. In some countries, quarantine rules, breed restrictions, or limits on the number of animals per person apply.
What to Do During a Delay or Route Change
A separate plus of the new document is the attention to abnormal situations. A delay, cancellation, diversion of the flight, or route change with an animal is more complex than a regular passenger rebooking. If the flight is postponed for many hours, the animal may remain in the container for a long time. If the route is changed through another country, new requirements for transit or import may arise. If the passenger is transferred to another carrier, that carrier may not accept pet in cabin on the same terms.
IATA advises airlines to have procedures for such cases: quickly inform passengers, assess the animal's needs, coordinate with ground services, veterinary or airport structures, and also consider documents when changing jurisdiction. For the traveler, the practical conclusion is this: in trips with animals, it is better not to build a route on minimum connections, separate tickets, and complex overnight transfers, if there is a simpler option.
What a Passenger Should Do Before the Trip
The new IATA initiative does not shift all responsibility to the airlines. On the contrary, it makes obvious that the passenger remains responsible for compliance with the rules of the entire route. Before buying a ticket, it is worth checking the policy of each airline, the type and size of the allowed animal, container requirements, the number of animals per flight, the cost of the service, application deadlines, transit rules, and the country of arrival.
- Confirm pet transport directly with the airline, especially if the ticket is bought through an intermediary.
- Check if all route segments accept the animal in the cabin, not just the first flight.
- Select a container according to the specific requirements of the carrier and accustom the animal to it before the trip.
- Prepare medical documents, vaccinations, certificates, permits, and import rules for the destination country.
- Clarify the rules of transfer airports, the availability of pet relief areas, and the possibility of leaving the transit zone.
- Allow extra time for registration, security control, transfer, and possible additional questions from staff.
Why This Is Important for Tourism
For the tourism market, the new IATA guidelines may be a step toward more standardized pet-friendly travel. This does not mean that all airlines will immediately allow more animals in the cabin or lower fares. But if carriers implement clearer rules, passengers will be able to better compare options, plan longer trips, and reduce the risk of boarding denial at the last moment.
Those travelers who do not transport animals also benefit. Consistent procedures reduce chaos at the gates, help the crew know about animals on board in advance, allow for the consideration of allergies or phobias of other passengers, and reduce the risk of conflicts in the cabin. For airports, the topic is also practical: if the demand for such travel grows, infrastructure for transit with animals becomes not an additional luxury, but part of a normal passenger experience.
The main conclusion for tourists is simple: the new IATA guidelines make traveling with a dog or cat more understandable, but they do not remove the need for preparation. Before booking, it is necessary to check the carrier's rules, documents, container, route, and the requirements of the country of arrival. In pet travel, there are almost no trifles: one incorrectly chosen bag, a missing certificate, or an unconfirmed service can ruin the entire trip.
