Traveling with a pet: rules for flights and borders
Check the airline's pet policy and the destination's import rules before you book: cabin space, carrier size, health-certificate window, fees and any quarantine are set by the airline and the destination, not by a single global rule. Skip the trip with the pet if the destination bans the species or the airline has no pet slot left.

Short answer
You can usually fly with a dog, cat or small pet, but two separate rulebooks apply: the airline's (carrier size, cabin vs cargo, number of pets per flight, fee) and the destination country's (microchip, rabies vaccination, health certificate, import permit, quarantine). Neither is standardised, so the answer for your trip comes from your airline and your destination's agriculture or border authority, not from a general guide.
Plan backwards from the flight date. Border paperwork has a validity window, so a certificate issued too early can be refused on arrival, and a permit that has not arrived in time can stop the trip. Book the pet slot when you book your own ticket, because many airlines cap pets per cabin and per flight.
If the destination bans the species, the airline has no pet slot, or the animal cannot fit the airline's carrier limits, the practical answer is to leave the pet at home or use a licensed pet relocation service. Check every figure on this page against the airline and the destination authority before you pay for anything.
Do
- Start with the destination's official animal-import page, then match it to your airline's pet policy.
- Keep a scanned copy of every document on your phone as well as on paper.
Who does it apply to?
This applies to anyone taking a dog, cat or other pet on a commercial flight, and to anyone crossing a border with that animal, whether by air, road, rail or sea. It covers pets travelling in the cabin and pets travelling as checked baggage or cargo.
It does not cover the same ground as service-animal rules. Assistance dogs are handled under separate airline and border provisions, and the documentation differs from pet paperwork. Check both the airline and the destination authority if you travel with an assistance dog.
Rules also vary by species. Dogs and cats are the most commonly accepted; birds, reptiles, rodents and ferrets face extra restrictions or outright bans in some countries. Check the destination's list before assuming your pet is allowed in.
Do
- Confirm the rules for your exact species, breed and route, not just for "pets" in general.
Watch out
- A pet that arrives without the correct documents can be quarantined, returned or, in some cases, put down. Check before you fly.

Step-by-step process
1. Read the destination's official import rules for your species. Note the microchip requirement, the rabies vaccination timing, the health-certificate window and whether an import permit or quarantine applies. Check each of these against the authority's own page.
2. Check your airline's pet policy for the route and aircraft. Confirm whether the pet can travel in the cabin or must go as checked baggage or cargo, what carrier size and weight limits apply, how many pets are allowed per flight, and what the fee is. Check the current figures with the airline.
3. Book the pet slot at the same time as your own ticket. Many airlines limit pets per cabin and per flight, and some routes do not carry pets at all. Check availability before you commit to a fare.
4. Visit your veterinarian. Get the microchip implanted if the destination requires one, confirm the rabies vaccination meets the destination's timing rules, and ask the vet to issue the health certificate inside the destination's validity window. Check the exact window with the destination authority.
5. Apply for an import permit or any other destination approval if one is required. Check the processing time with the authority and apply early enough to allow for delays.
6. Buy a carrier that meets your airline's published dimensions for cabin or cargo. Check the size, weight and ventilation rules for the specific airline and aircraft.
7. Confirm the airport procedure with the airline before travel day: check-in desk, cut-off time for pet acceptance, and whether the pet is handed over at check-in or at a separate animal reception point. Check the airline's own guidance rather than relying on general advice.
8. On arrival, present the pet's documents to customs or the border agency. Check whether the destination requires a declaration, an inspection or a fee on entry.
Do
- Work backwards from the flight date and put every deadline in a calendar.
- Ask the airline to confirm the pet booking in writing before you pay for non-refundable travel.
Watch out
- If the carrier does not meet the airline's limits, the pet may be refused at the gate or moved to cargo. Check the carrier against the airline's published rules before travel day.
Cost and time overview
Pet travel has several separate costs, and none of them is fixed across airlines or countries. Check each one directly with the airline, your veterinarian and the destination authority before you budget.
The airline pet fee depends on the carrier, the route and whether the pet travels in the cabin, as checked baggage or as cargo. Check the current fee for your specific flight.
The carrier, the veterinary examination, the health certificate, any microchip or vaccination, an import permit and any quarantine kennel charges are separate. Check the price of each with the provider that issues it.
On timing, the binding constraint is usually the destination's health-certificate window and, where required, the permit processing time or quarantine period. Check both against the destination authority's own page, because they differ by country and can change.
Do
- Ask the airline and the destination authority for written confirmation of fees and deadlines before booking non-refundable travel.
Watch out
- Quarantine, if required, can add weeks and a substantial kennel cost. Check whether your destination requires it before you plan the trip.
Exceptions and special cases
Service and assistance animals are treated under separate rules from pets by most airlines and border agencies. Check the airline's assistance-dog policy and the destination's entry rules, because the documentation and any fee differ from pet paperwork.
Some destinations require quarantine for pets arriving from certain countries, even with complete paperwork. Check whether quarantine applies to your route and how long it lasts with the destination authority.
Some airlines restrict or refuse flat-faced (brachycephalic) breeds, and many have seasonal heat embargoes on pets in the hold. Check the airline's breed and temperature rules for your travel dates.
Some countries ban certain species outright, and some restrict the number of pets one traveller may bring. Check the destination's prohibited-species list and per-traveller limits.
Returning home can be harder than leaving. Check your own country's re-entry rules for pets before departure, because they may require documents issued before you left.
Do
- Check the rules for the return leg at the same time as the outbound leg.
Watch out
- A destination that accepts pets may still quarantine them on arrival. Check before you fly, not after.
Cabin vs. cargo vs. pet relocation service
Cabin travel keeps the pet with you, but only if the animal and carrier meet the airline's cabin limits. Check the airline's size and weight rules for your flight.
Checked baggage or cargo allows larger animals, but the pet is handled separately from you and the airline's rules on temperature, breed and connection times apply. Check the airline's cargo policy and any embargoes.
A licensed pet relocation service handles permits, bookings and transport for a fee. It is useful for complex routes or tight deadlines, but you still own the responsibility for meeting the destination's rules. Check the company's credentials and the total cost before committing.
| Option | Cost | Pros | Cons |
|---|---|---|---|
| Cabin | Check the airline's cabin pet fee | Pet stays with you | Strict carrier size and weight limits; limited slots |
| Checked baggage or cargo | Check the airline's cargo fee | Suits larger pets | Separate handling; breed, temperature and connection rules |
| Relocation service | Check the company's quote | Handles paperwork and booking | Extra fee; you still must meet destination rules |
Fees and limits change by airline, route and aircraft. Check each figure with the provider.
Questions people ask
Traveling with a pet: what is the short answer?
Two rulebooks apply: your airline's pet policy and the destination country's import rules. Check the airline for carrier size, cabin or cargo, slots and fees, and check the destination authority for microchip, rabies vaccination, health-certificate window, import permit and quarantine. There is no single global standard.
Who does it apply to?
Anyone flying with a dog, cat or other pet, and anyone crossing a border with that animal by any mode. Service animals and unusual species follow different rules, so check the airline and the destination authority for your case.
How much does it cost and how long does it take?
Costs and timing are not standardised. Check the airline pet fee, the carrier price, the veterinary and certificate charges, any import permit fee and any quarantine kennel cost with the providers themselves. Check the destination's certificate window and permit processing time before booking.
Can I bring a pet in the cabin on a long-haul flight?
Only if the pet and carrier meet that airline's cabin limits, and only if a cabin slot is available on that flight. Check the airline's size, weight and route rules, because they differ between carriers and aircraft.
Do service animals need the same paperwork as pets?
Usually not. Assistance dogs are handled under separate airline and border provisions, and the documentation differs from pet paperwork. Check both the airline's assistance-dog policy and the destination's entry rules.
What happens if my pet's documents are wrong on arrival?
The border agency can refuse entry, quarantine the animal, return it or worse. Check every document against the destination authority's own page before you fly, and carry copies.
