Airline pet policies: what to know before you book
Airline pet policies vary widely and change often. Booking a flight without checking pet policy can result in the pet being denied at the gate. A 15-minute call before booking saves a missed trip.

Quick answer: Before booking: confirm the airline accepts pets on your route, in cabin or in cargo. Confirm carrier size, weight limit, breed restrictions, and seasonal embargoes. Get health certificate timing from your vet. International travel adds country-specific entry requirements; start the paperwork 3 to 6 months early.
In-cabin vs cargo
In-cabin pet travel is generally limited to small dogs and cats whose carrier fits under the seat. Most airlines cap combined pet-plus-carrier weight at around 15 to 20 lb. Larger pets fly in cargo or via specialized pet shipping services.
Cargo travel has additional rules — airline policy, IATA carrier standards, temperature limits, breed restrictions for short-nosed (brachycephalic) breeds.
What to confirm before booking
- Pet policy on the specific route (codeshare flights may not allow pets)
- Carrier dimensions — under-seat space differs by aircraft
- Weight limit for pet plus carrier
- Breed restrictions (many airlines restrict brachycephalic and certain large breeds)
- Seasonal embargoes — temperature-based holds in summer or winter
- Number of pets allowed per cabin — some flights are full when you book
- Fee — usually $95 to $200 each way
- Booking method — most pets must be added by phone, not online
Paperwork
Domestic US flights typically require a health certificate from a USDA-accredited vet within 10 to 30 days of travel. International travel requires Certificate of Veterinary Inspection (CVI), rabies titer (for some destinations), and country-specific endorsement through USDA APHIS.
Start the international paperwork 3 to 6 months in advance for many destinations.
Carrier prep
Soft-sided in-cabin carriers should be airline-approved for the route. Pre-acclimate the carrier weeks before the flight — leave it open with bedding at home so the pet gets familiar.
Skip food 4 hours before the flight; provide water as ice cubes in the carrier (they melt safely without spilling).
Day of travel
- Arrive 90 minutes early for domestic; longer for international
- Carry health certificate, vaccine records, microchip number, contact info
- Walk the dog before security
- Skip sedation unless your vet specifically prescribes — many sedatives are dangerous at altitude
- Bring small absorbent pads for the carrier
- Photograph the pet and carrier before drop-off (cargo); save the air-waybill number
How Driyu fits

Frequently asked questions
Can I take any size pet in the cabin?
No. Most airlines limit in-cabin pets to those fitting under the seat in an approved carrier, usually with a combined weight under 15 to 20 lb. Larger pets fly in cargo or via specialized pet shipping.
Do I need a health certificate for domestic flights?
Most US domestic airlines require a health certificate from a USDA-accredited vet within 10 to 30 days of travel. Confirm with the airline.
What about emotional support animals (ESAs)?
Most US airlines no longer accept ESAs as service animals after 2021 rule changes. ESAs travel as pets, subject to pet policies and fees.
Is sedation a good idea for nervous pets?
Most veterinary organizations advise against sedation for flying — it can affect breathing at altitude. Discuss with your vet; pre-conditioning and pheromone sprays are safer for most pets.
