I have flown on United, US Airways, and American with my 2 yorkies. They all charge $100 each way. American was the only airline that actually checked my vet paperwork, etc., and confirmed that my boys were under six months and related (don't ask, weird policies for 2 dogs in one kennel). Anyway, I have no problems to report for these airlines.
Delta is probably the same policy and has a hub in Atlanta, so you might check them out.
Good luck! |
