it depends on the airline...but here's what American airlines lists as their requirements:
The maximum size for cabin pet carriers is 23" long x 13" wide x 9" high
Animals must be able to stand up, turn around and lay down in a natural position in the kennel.
Soft-sided pet carriers are accepted as long as they are constructed of water-repellent, padded nylon with mesh ventilation on two or more sides. |
