Airline Pet Policies and Dog Carrier Dimensions

We've had a lot of questions about acceptable carrier sizes for air travel, so we put together the information below to help you determine the proper carrier size for your airline.

If you're planning to travel with your dog on an airplane, and carry them in the cabin with you, read your airline's pet policies to be sure you comply with their current requirements regarding pet carriers (you can click the links below).

This information is what's available on each airline's website as of 10-1-2012, and is subject to change without notice by an airline.  Click a link below to access the airline's most current requirements.

NOTE:  Many airlines are only accepting carriers that have metal crate hardware - no plastic fasteners.  Please carefully read the descriptions on the carrier you're choosing for airline travel, and ask us if there are any questions.  Thank you.

Common Requirements:

  • Must be big enough for dog to stand up, turn around, and lie down naturally and comfortably in the kennel/carrier. Dog cannot protrude out from the carrier.
  • Must fit under the seat directly in front of you.
  • Must be leak-proof, escape-proof and ventilated on at least 2 sides.
  • Must not exceed specific dimensions, listed below for each airline.
  • May need to have only metal crate hardware.
