** These rules apply to in-cabin animals only. Some airlines do allow checked or cargo animals, but this calls for completely different rules and fees. Service animals also have totally different regulations.
If we must pick the most pet-friendly US airline, JetBlue takes the cake with Southwest a close runner-up. Not only do both airlines offer approved-size pet carriers for sale, but their pet travel info pages are robust. Add to this the fact that both airlines don't charge more than $100 for an in-cabin pet and don't charge for your first checked bag (which is important as you'll likely be checking a bag since your pet carrier counts as a carry-on), and you've got winners. JetBlue's bonus 300 TrueBlue points for each pet flight leaves them the leader of the pack.
