I was chatting to an EasyJet crew on a jumpseat ride about the forthcoming delivery of the 737NG, and they said that the CAA would not allow EZY to operate three different 737 cockpits - some of EZY's 737-300s have 'clockwork' cockpits. I think these aircraft were from Southwest (the WN a/c only have a single FMC as well!) and Monarch. If Stelios wanted to operate the NG and the glass -300, the clockwork cockpits had to go, and they have now left the fleet, or are for sale.
So much for Boeing's assertion that the 737-3/4/500 and NG is a single type, the CAA don't even consider two different versions of the -300 to be similar enough to fly alongside each other, at least, not at an airline of EasyJet's stature.
(I'm sure I mentioned this before, hope it's not on the same thread from a few months ago. D'oh!)
