Pet Travel Rules: Flying & Crossing Borders With Your Dog

Flying With a Dog in the Cabin: What to Check

Each airline sets its own pet policy, fee, carrier size and limit per flight; check the airline's pet page before booking (U.S. DOT).

• Book the pet when you book your seat; in-cabin spots are limited per flight.
• Carrier must fit under the seat in front of you.
• Fees run $125–$150 each way on major U.S. airlines: see airline pet fees for 2026.
• At TSA, the pet comes out of the carrier and the empty carrier goes through the X-ray (TSA).
• Since 2021, DOT rules let airlines treat emotional support animals as pets; only trained service dogs keep service-animal status (DOT).
