Worrying about buying a cat carrier or a dog carrier that will not fit under a plane seat is a thing of the past. Sleepypod's folding system allows pets to travel in the largest space possible while the airplane is in the air, yet still allows for stowage under an airline seat. When the captain says you can recline your seat, rotate the Sleepypod Air so it is between your feet and then expand the ends so both you and your little friend can stretch out comfortably for the duration of the flight. In-cabin pet travel has never been so comfortable. Some airlines allow passengers to carry their pets in the cabin of a plane if your pet is capable of fitting in an airline-compliant under the seat in front of you. Carry-on pets are not regulated under the Animal Welfare Act; however, the airlines will require that your pet be able to stand up and turn around in the carrier. For animals other than dogs or cats, contact the airline for their acceptance policy. You can also send us an email at or post an inquiry on our .

The under-seat dimensions are as follows: window seat - 19" L x 14" W x 8.25" H; middle seat - 19" L x 19" W x 8.25" H; aisle seat - 19" L x 14" W x 8.25" H.

Pets must be secured in the pet carrier at all times while in the gate area, during boarding/deplaning, and they must remain in the carrier for the entire duration of the flight. Failure to follow this requirement may result in denial of transportation of the pet onboard Southwest Airlines.
