A dog's first flight begins long before the airport. Before you choose an airline and a carrier, assess your dog's health, its reaction to confinement and its resilience to new stimuli. This guide is updated for the 2026/27 travel season; airline policies and import rules change, so confirm the details before you pay for anything.
Is your dog ready for its first flight? Assess the animal first, buy the ticket later
The easiest mistake is to start from a flight search engine. A low fare and a short flight time say very little about how a specific dog will cope. Look first at health, previous transport experience, the reaction to confinement and behaviour around strangers and intense stimuli. A dog that sleeps in a carrier during a car ride is in a very different position from one that starts panting and scratching at the door after a few minutes of confinement.
Tolerating a carrier at home is not enough: an airport means noise, queues and waiting, then security, boarding, take-off and landing. If a dog panics when confined, salivates heavily, chews the carrier or tries to force its way through the walls, do not assume it will 'somehow get used to it' on the plane.
Health is the second filter. Respiratory and circulatory diseases, fainting episodes, thermoregulation problems and chronic conditions all call for a veterinary consultation before you book, not after the ticket is paid for. Brachycephalic (short-nosed) breeds are a separate group: some airlines do not accept them in the hold at all, so check the rules for the specific breed, method of carriage and route.
Prefer a short direct flight for a first trip, and on short European routes compare it with a car or train journey. The key test is not 'can a dog fly?' but 'is this particular flight a reasonable journey for this dog?'.
Cabin, hold or cargo – the method of carriage changes the whole preparation
Where the dog travels determines everything that follows. Check what the specific airline allows on the specific flight first, and only then prepare the dog and the equipment. Rules differ between routes and aircraft types, so the statement that an airline 'accepts dogs' is far too general.
Dog in the cabin
Airlines set their own limits on the combined weight of dog and carrier, the dimensions of the bag and the number of animals per flight. The carrier usually goes under the seat in front of you, and that space varies by aircraft – one of the classic cabin luggage dimension traps. A carrier sold as 'airline approved' is not automatically accepted by every airline.
Dog in the hold
The animal is accepted only if the airline and the aircraft type allow it and the operational conditions are met. The dog should be able to rest in the container without you next to it.
Cargo
Cargo means the dog is handled as a live-animal air shipment rather than as an animal accompanying a passenger. Acceptance and collection may take place at a separate cargo terminal.
| Method | Contact with the owner | Carrier | What to train |
|---|---|---|---|
| Cabin | The dog stays close but remains in the carrier | A model that fits the airline's limits and suits the dog | Staying calmly confined despite the owner's presence |
| Hold | No access to the dog after handover | A container compliant with the airline's requirements | Resting independently, separation and being moved |
| Cargo | A procedure separate from the passenger journey | A container compliant with cargo and airline requirements | Staying in the container for longer without the owner |
Booking a ticket with a dog – do not assume a spot for the animal will appear automatically
Booking a seat for the passenger and registering the dog are two different things. Airlines limit the number of animals per flight, so check whether the dog can be carried on the specific flight first and only then finalise the ticket, especially a non-refundable one. Be ready to give real measurements: dog weight, weight with carrier and carrier dimensions.
Connections need extra care. Carriage must be confirmed for each leg, codeshare flights may be operated by another airline, and acceptance by the first carrier does not bind the next one. Cabin rules vary widely, as ITA Airways' cabin baggage rules show. For a first trip the best booking has the fewest dependencies: one carrier, a direct flight and carriage confirmed well before check-in day.
Before paying, confirm the spot on the specific flight, the method of carriage, the weight limit for dog and carrier, the maximum carrier dimensions, breed and aircraft restrictions on every leg, the cost and registration deadline, and where the animal checks in.
Treat the pet fee as a separate budget item, because it depends on the airline, route and method of carriage. Remember too that a pet carrier in the cabin usually counts within your hand baggage allowance – the logic resembles taking two carry-on bags on board, so check what else you may bring. Keep the written confirmation with your travel documents.
Microchip, passport and vaccination – check the formalities well in advance
A dog's documents cannot always be sorted out a week before the holidays. For a trip between EU countries the preparations can be short, but some third countries and the return to the EU can require procedures spread over several months. A passport and an up-to-date health record do not on their own mean the dog meets every requirement.
Within the European Union
The basis is a microchip, a valid rabies vaccination and an EU pet passport issued by an authorised veterinarian. The order matters: the microchip must be implanted or read before the rabies vaccination that serves as the basis for travel. After the primary vaccination you generally wait at least 21 days, and the dog must be at least 12 weeks old at the first vaccine. A booster given within the validity of the previous one maintains continuity; if the deadline is missed, the next vaccination counts as primary again.
Not every European destination ends there. For Finland, Ireland, Malta, Norway and Northern Ireland, treatment against the tapeworm Echinococcus multilocularis carried out 24–120 hours before entry and properly documented is required. That is why formalities are checked for the specific destination, not against one checklist for the whole of Europe.
Outside the EU and the return to the EU
Check the destination country's regulations independently of the airline's rules. The United States, for example, applies its own dog entry system that includes minimum age, microchipping and a CDC Dog Import Form receipt, while the United Kingdom applies post-Brexit rules of its own. Where a rabies antibody test is needed, the blood sample is taken no earlier than 30 days after the primary vaccination and a 90-day wait may follow, so starting six or eight weeks before the holiday can be far too late.
Plan the return as well. If the required titration is performed with a positive result before leaving the Union and recorded in the EU passport, the 90-day wait does not apply on re-entry, and the test need not be repeated while rabies vaccinations remain continuously valid.
The country's regulations and the airline's rules are two separate sets of requirements. A dog can hold every border document and still fail the carrier's transport conditions, or be accepted by the airline and lack what the country requires on entry.
Which carrier for a dog on a plane? The size must match the animal and the airline's rules
Do not choose a carrier on the strength of an 'airline' label. Check the airline's rules, measure the animal and only then buy.
A carrier for the cabin
Measure the actual ready-to-use carrier, because pockets, protruding handles and stuffed walls increase the external dimension. At the same time do not solve the limit by buying a model that is too small: the dog must be able to adopt a natural position for the entire flight.
A container for the hold
The current IATA guidelines require the animal to be able to stand, sit in a natural position, lie down and turn around freely, with a smooth interior, a leak-proof floor, ventilation and a secured door. IATA publishes standards but does not certify specific brands, so there is no model that every airline must accept.
Take four measurements with the dog standing naturally: A, nose to base of tail; B, ground to elbow; C, width across the shoulders; D, ground to the top of the head or ears, whichever is higher.
The minimum internal length is A + ½ B, the width is C × 2 and the height is E = D + the height of the bedding. For short-nosed breeds the current requirements provide for a container 10 percent larger, which still does not oblige an airline to carry them in the hold. If the container has wheels, the airline may require them to be removed or immobilised.
Your own luggage on a trip with a dog: which Peli model for what
A hard suitcase or protective case is useful for your own belongings, spare equipment and the dog's accessories – the question of hard or soft luggage is worth settling first. Peli products do not replace a container for the animal: the dog travels only in a carrier or container intended for that purpose and accepted by the airline. Dimensions and weights below come from the product pages.
| Model | External size (cm) | Weight | Volume | Best use on a dog trip |
|---|---|---|---|---|
| Peli Air 1535TRVL | 55.8 × 35.5 × 22.8 | 4.7 kg | – | Cabin case for documents, electronics and the dog's essentials |
| Peli ATX HC22 | 55.9 × 35.6 × 23.1 | 4.8 kg | 30 L | Cabin hard case for a 3–5 day trip |
| Peli Aegis HY22 | 36.6 × 26.9 × 55.9 | 3.32 kg | 47 L | Soft-hard rolling duffel when you refuse to check a bag |
| Peli Aegis PX18 | 27 × 16 × 46 | 1.22 kg | – | Backpack for papers, medication and the laptop |
| Peli ATX HC25 | 66 × 45.7 × 26.9 | 8.39 kg | 70 L | Check-in case for a week away |
| Peli ATX HC30 | 76.2 × 50.8 × 30.7 | 9.93 kg | 90 L | Large check-in case for a long stay |
| Peli Aegis HY32 | 40.6 × 38.1 × 76.2 | 4.76 kg | 115 L | Very large, light duffel for bulky non-fragile gear |
A compact bag such as the PX18 backpack or the Air 1535TRVL leaves more room next to the carrier.

Getting your dog used to the carrier – start the training before departure day
The carrier should become an ordinary, safe place long before the day of the flight. Leave it open in a quiet spot and let the dog approach on its own, sniff the interior and go in for a treat or a chew. Close the door only later, at first for seconds with you right next to it, and end each session before the dog starts fighting to get out. When anxiety appears, shorten the next attempt instead of waiting out a panic.
With carriage in the hold, separation is added: once confinement is calm, step away for a moment and come back before the dog starts to worry. Then add movement – lifting the carrier and short car rides. The pace is set by the dog's behaviour, not the departure date. If the deadline forces you to hurry, change the plan. With recurring panic or self-injury, discuss further preparation with a veterinarian and a dog behaviour specialist.
Vet, food, water and medication – health preparation before the first flight
Give the vet a concrete plan: method of carriage, flight length, time at the airport, connections, destination and season. A two-hour flight can mean six or seven hours of travel once you add the airport and the transfer.
Sedatives – do not experiment on the day of the flight
Current animal transport guidelines warn against routine sedation during flights. Do not give a new preparation just before check-in; any drug, dose and timing should be decided by a veterinarian who knows the dog. Airlines may refuse animals that have been sedated.
Feeding and hydration
There is no single correct time for the last meal. Stay as close as possible to the normal rhythm, avoid a large meal just before leaving and do not introduce a long fast on your own. A dog on insulin or other scheduled medication needs a plan agreed with the vet, and medication should stay with you, not in a suitcase you cannot open after check-in. Carry water and a little familiar food in case of delay.
Flight day with a dog – from the last walk to handing over the carrier
Keep the day predictable: a normal rhythm, a calm walk and time to relieve itself, not a long run. Check the documents, the confirmation of acceptance and the carrier's equipment once more. Keep papers and medication in hand luggage – a small Peli 1060 waterproof case for phone and documents is one way to keep them dry and together. Do not put anything in checked baggage that you may need before bag drop or during a delay.
Arrive with a buffer that matches the airline's procedure for animals, not the minimum for a regular passenger. A dog in the hold is handed over at a designated point and the container may be inspected. In the cabin, be ready to take the dog out of the carrier at security if staff ask; a well-fitted harness and leash are essential, and the carrier is screened separately – officers see plenty of strange things in carry-on baggage, but a live animal follows its own procedure.
In your own bag keep the documents, a leash and well-fitted harness, an absorbent pad and waste bags, water and a collapsible bowl, medication, a little familiar food and your contact details.
In the air and after landing
In the cabin
Follow the airline's rules and the crew's instructions, even if the dog is calm. Whining or short spells of faster breathing do not mean the carrier must be opened. Limit your own movements, speak calmly, avoid large numbers of treats and never give a new sedative in flight.
In the hold
After handover you have no access to the dog, which is why the measurements, the crate, the closure check and the training in staying inside alone matter so much. If the flight is delayed or cancelled, tell staff immediately that an animal is part of the journey and establish its status – the same lesson that applies when you have missed your flight yourself, only with higher stakes. A new flight may require the dog's carriage to be reconfirmed.
After landing
A dog from the hold is not always released at the regular belt; it may be handed over at the oversized baggage point or under the cargo procedure, so find out where to report before the trip. Inspect the container, then let the dog out on the leash in a place you can control. Offer a walk, water and quiet rest.
Clear breathing difficulties, weakness, coordination problems, loss of consciousness or repeated vomiting need prompt veterinary assessment, so know where the nearest clinic is.
FAQ: first flight with a dog
Can any small dog fly in the cabin?
No. Weight alone does not decide. The airline limits the combined weight of dog and carrier, the carrier's dimensions and the number of animals per flight, and restrictions can depend on the aircraft type.
How early should I start the paperwork?
As early as the route is chosen. Within the EU the basics are a microchip, rabies vaccination and a passport with a 21-day wait after the primary vaccine, while some third countries and the return to the EU can take several months.
Should I sedate my dog for the flight?
Not on your own. If medication is considered at all, a veterinarian who knows your dog should decide well before departure day.
