Daifly
A long-time neighbour and good friend works for a large European company and occassionally travels to the far east. He's gone off BA after a couple of funny experiences.
He checks in and manages to get his favourite seat upstairs, during the flight he has been asked to move....the excuses being rather lame ....something to do with serving or for his convenience or whatever; it is transparently obvious to him that it is to accommodate groups of jeans-and-Tshirt staffer upgrades in their own select little area.
He doesn't fly BA any more.
This is only hearsay, therefore classify as rumour only, but he has no reason to lie.
