If you’re looking for information about an airline’s main cabin carry-on pet policy for when you fly with your cat, here are summaries of the major ones nationwide. Please note, this information does not apply to certified service or support animals.
Generally, all carriers must have a leak-proof bottom and be well-ventilated, and your cat must be able to fit comfortably enough to stand up and turn around with ease.
One pet carrier per passenger is usually the limit, and most are considered as one item in your carry-on allowance. That means you can have two carry-on items: your cat carrier and a personal item; or your cat carrier and a regular size carry-on bag. If you board with all three, you may be charged extra, so look at your airline’s rules carefully.
The fees tend to be per carrier, one way. Each fee is “per flight segment,” so if you do have any stopovers, you may be charged an additional one. Ask before you book.
Airlines also require that your cat be “harmless, not disruptive, odorless, and require no attention during flight.”
While strollers for children are generally checked at the gate and returned to you before you disembark, there is no confirmation that this is the case if you’re bringing your cat stroller on your flight. So, you’ll need to check the airline’s policy, and also confirm that it is in addition to your carry-on allowance.
And if you’re wondering why it’s hard to bring your cat to Hawaii, that’s because it’s the only rabies-free state in the US. To keep it that way, strict documentation protocols are enforced. Animals without proper documentation can be quarantined for up to 120 days in Honolulu at the owner’s expense. You can read more at the State of Hawaii Animal Quarantine Branch.
Below you’ll find the main information for the carry-on pet policy of 11 major US airlines with a direct link to their website pet page and contact phone number. Make your reservation as early as possible: the number of pets per cabin is limited, and most airlines observe a first-come, first-serve policy.
