Well i've heard a lot about 737's taking over the 757's and I'm sure it is going to happen. I've heard about that from a few trainers actually so could well be true...
The MD did confirm that he will be signing contracts either with airbus or boeing within the next few months, but these aren't due to come into service until 2011 so we have a while!!!!
The whole Britanniafly thing sounds a bit fishy to me...I doubt we would change so quickly after doing this whole campaign thing for Thomsonfly so I'd take that with a pinch of salt to be honest!
