sunday feb 18th, ba 872 lhr to krk, around 11am I noticed the blocked middle beside me had already become occupied so I knew it was a busy flight
shortly after check in closed I noticed on the app my seat had been changed from 10A to 3C(the last row in a small CE cabin)
got new boarding passes printed in the lounge and saw my boarding group had gone from group 2 to group 1 as part of the op up
