Since United and Turkish are both Star Alliance, I can buy the entire ticket from Turkish and fly from my small city to a big airport (such as ORD) with United, then to Turkey (or wherever) with Turkish.
I need to do this with a medium-sized dog. If I make the arrangements with Turkish, does this imply that the first leg with United will be covered as well? If United normally doesn't transport dogs domestically under the same rules (or at all) am I out of luck?
How does one typically fly with dogs with two airlines?
Edit: the dog will be pet cargo, it's too big to go under the seat.
