· Virgin America: $100
Virgin America ranks very high on the pet friendliness charts, as they not only fly the pets of passengers, but they also regularly fly rescued chihuahuas from the west coast to new homes on the east coast. Oh, and Virgin America has a "pet liaison" Pomeranian, Boo, and you can purchase a branded pet hoodie in their online swag shop. Despite all this, the pet travel info page desperately needs improvement. Pets are only allowed in Main Cabin seating on Virgin America. To book a flight for you and your pet, you must call 1.877.FLY.VIRGIN.
Carrier size restriction: 18"L x 15"W x 8"H
** 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.
