But you got the J upgrade on your way back sitting next to me. Totally agree with being nice though.When I took my LTG flight which was ADL MEL, I took boxes of chocolates with me (from a WW EDR special ) and I gave one of the boxes to the ADL QP staff to celebrate. They then came to see me later in the QP to offer me an upgrade. Trouble was, I was already in 2C
Anyway, my point is, if you are nice to them, you never know what they might be able to do. Just asking however is unlikely to do it IMO, no matter how polite you are.
