I have a multi-leg itin tomorrow. I checked in 24 hours in advance. I was able to move my seats. And I was happy w/ them. When I just checked my itin on united.bomb, it showed different seats then I had checked in for. What's the deal? Anyone have this happen to them before? Will I be stuck in the seats I DON'T want? Thankfully, my one mainline flight, the seat didn't change.
