Mixed itin can I check in at gate
So I am on a United award with 2 United flights and then a leg in TK from Bru-ist I was unable to select seats either via app or the help desk. I'm within the 24 hr check in window so I assume the help desk will be of no use now.
My question is on arrival at BRU, will we be able to go to the gate and check in there or do we have to go thru passport control to use the check in counters.
Thanks for any thoughts.
