Can a friend travel with my dog via airplane? Or do I, the owner, have to also be there? I'm trying to send my dog to my parents in one state while I fly somewhere to a different state first, but cargo rates for live animals are insanely expensive. When I last traveled with my dog (on the same flight) it was only $100. I have a friend who is traveling to where my parents live and would be willing to 'take' my dog, but is that ok?
