dicannio10 - I would rather have a stop in Bangor than lose £200, maybe not a lot of money to you but it is to me.
p.s. before anyone says why pre-book seats when all this uncertainty I didnt know anything about the uncertainty, possible plane changes, delays etc when we booked, it was only a month ago or so I found all this out, if I had known then what I know now I wouldnt have parted with more hard earned cash to pre-book seat that I might not even get if it is not a 757.
