It’s a credit to you that you remained pragmatic, enjoyed the flight and didn’t let the seat change affect you too much.

It’s certainly worth chasing up regarding the reason for the move. Of course there is the disclaimer from BA that seat changes may be required for operational reasons. Hence whilst they are not obliged to, in the interests of good customer relations and retaining your business, it would make sense for BA to investigate without fobbing you off and give you an explanation for the seat change.

When coming back from Malta recently, my family and I were simply booted from our preassigned seats in CE around 2 days before the flight (when I happened to go into the MMB to request child meals for our boys, I noticed ‘seat choice available’ rather than our presssigned seats in row 3). I was able to allocate row 4, which was fine. On board, row 3 had single passengers. There was no outwardly obvious reason for the move. I rung up customer relations who apologised and awarded 8000 Avios. So whilst I’ll never know why we were booted, the goodwill gesture of Avios and acceptance by BA that the situation should not have occurred was appreciated.
