U.S. airline pet policies for in-cabin travel

The following information (including whether dogs are allowed to fly in-cabin, maximum carrier sizes, and fees charged) has been collected from the airlines’ published pet policies, supplemented (in some cases) by telephone inquiries. It was last updated on February 18, 2016.

For each airline, I have provided a link to the airline’s pet policy. It is a good idea to print out a copy of your airline’s policy, so that if a dispute arises with a ticketing or gate agent, you will have the actual policy to refer to (not the agent’s potentially faulty memory of the policy).
