Step-by-step guide to flying with your dog in the USA. Covers booking, health certificates, carrier rules, and airport tips.

Last updated: June 2026

Quick Answer

  • Book your dog's spot early — most airlines limit cabin pets to 2–4 per flight.
  • Get a vet health certificate within 10 days of your departure date.
  • Use a soft-sided carrier that fits under the seat (max 18×11×11 inches).
  • Arrive at the airport 30 minutes earlier than usual for pet check-in.
  • In-cabin pet fees range from $75 to $200 one-way on U.S. airlines.

About This Guide

This guide compares pet travel policies across major U.S. carriers. All fees and policies are verified against official airline sources and updated for 2026. Prices shown are one-way in-cabin pet fees unless otherwise noted.

When choosing an airline for pet travel, consider not just the pet fee but also the total ticket cost, carrier size requirements, weight limits, and route availability. A cheaper pet fee on a budget airline may be offset by fewer route options or stricter carrier dimensions.

Key Considerations for Pet Travel

  • Health certificate required within 10 days of travel (cost: $50-$200)
  • Airline-approved soft-sided carrier must fit under the seat in front of you
  • Most airlines limit in-cabin pets to cats and dogs under 20 lbs (carrier included)
  • Round trip pet fees are typically double the one-way fee
  • Cargo fees range from $200-$1,000+ for pets that cannot fly in cabin
  • International travel requires additional documentation (import permits, microchips, titer tests)

Frequently Asked Questions

What documents do I need to fly with my dog?
A vet health certificate issued within 10 days of travel, proof of rabies vaccination, and your airline's pet booking confirmation. International flights may require additional documents.
Can I buy a seat for my dog?
No. U.S. airlines do not sell seats for pets. Your dog must stay in an approved carrier under the seat in front of you throughout the flight.
How early should I arrive at the airport with my dog?
Arrive at least 30 minutes earlier than you normally would. You'll need extra time for pet check-in and security screening.
Can my dog come out of the carrier during the flight?
No. Your dog must remain inside the carrier for the entire flight, including during takeoff and landing. The carrier must stay under the seat.
What happens if my dog barks during the flight?
Airlines may ask you to calm your pet. In extreme cases, you could be asked to move. Familiarize your dog with the carrier before the trip to reduce anxiety.
