That was my thought too Ryan. That if you have a ticket, that is binding, you have already paid for the services even if they have not delivered yet.
It would be as bad as if, you bought something,paid a price and then they came and said, sorry we just changed the price, now you have to pay us more or we will take the..... back!
I shipped Galahad from MN when he was a puppy, it was in spring time we paid like $200, he could have gone in an intermediate crate for about $100 but we wanted him in an large one.
Good luck to you, I hope you get home okay. Or you can stop in NC with your mastiffs and say hi to Galahad and Hera.
Merry Christmas Ill keep my fingers crossed for you
