I’m looking at booking a flight on TK to Europe for the Fall. I’ll be using Mileage Plus miles booking on the UA site. If our plans change and we have to book another flight, how quickly are the miles out back on your “bank?” Will we be able to immediately rebook on a different airline? We don’t have enough miles to book another round trip without the redeposit.

Any tips on booking on TK via UA? I’ve read getting your seats selected is a challenge due to a glitchy TK website. I want to make seat selections as far in advance as possible. I’m hoping it’s as easy as going to their app or website, plugging in the TK confirmation number, and picking seats.

Thanks.
