the one time I have been upgraded was on a staff journey and the staff knew and came over and had a chat. I was amazed at the treatment that i received, no diff from a full fare pap and i have vowed to myself that i will never ring that bell no matter if I am in Y or J. I know how I would feel if I was expected to come to someone when they ring a bell.
working in reservations, the number of people who think that they should get an upgrade is amazing, they seem quite put out that as a low cost airline the only place to upgrade them to is the flight deck and that those seats are generally full. besides, when only paying £20 for a ticket, what do they expect..
