I didn't notice that last night, but I did something that I don't recall being able to do in the past. Around 8AM yesterday I checked in, selected my seat and printed my boarding pass. Around 8PM yesterday, I determined that I'd have to be reviewing some confidential documents on my laptop during that flight. So, now I needed a window seat near the back of the cabin (rather than aisle seat near the front). Again, I don't recall being able to do this in the past... but I logged into OLCI and changed my seat as well as printed a new boarding pass.

Could you always do that?
