Service Dog on a Plane — Airline by Airline Guide

Federal Rules That Apply to All Airlines

Under the Air Carrier Access Act (ACAA) and DOT regulations, all US airlines must allow trained service dogs in the cabin at no charge. Airlines may require advance notice and documentation, but cannot deny access to a legitimate service dog.

What Most Airlines Now Require

Following 2021 DOT regulation updates, most airlines now require:

• Completion of a DOT Service Animal Air Transportation Form
• Advance notice of 48 hours before the flight
• The dog to fit at the handler's feet or on their lap
• For flights over 8 hours: a DOT Relief Attestation Form

American Airlines

American Airlines accepts trained service dogs in the cabin. The DOT form must be submitted at least 48 hours before departure. The dog must fit within the handler's seating area without blocking the aisle.

Delta Air Lines

Delta requires submission of the DOT service animal form and advance notification. Delta has specific breed restrictions that do not apply to service dogs — all trained service dogs are accepted regardless of breed.

United Airlines

United Airlines requires the DOT form submitted 48 hours in advance. The airline also requires the handler to confirm the dog's behavior and training in writing.

Southwest Airlines

Southwest Airlines accepts trained service dogs with the DOT form submitted in advance. Southwest does not charge pet fees for service dogs.
