Would it not make sense for Glasgow to receive the 737-800's (If we ARE actually getting any, as it's a new base - so why not start small with the required NG equipment there first?)
I would expect Leeds to maybe one of the last bases to get the -800's, purely because of the amount of spares and stock held here.
Who knows what the plan is, we are yet to see any new aircraft and I'm sure any decisions will be fully thought through. I would imagine that the -300QC aircraft will be fully depreciated by 2013 so it would be cost effective to only use them for cargo operations, thus no need for a replacement as such - allowing any 'new' aircraft to only operate passenger flights at the QC bases.
My thoughts would be that GLA and EMA will get the new ones first - lets see what happens.
