Oh God yeah... I think there will be "certain" bases that get all the new 738's before others. Bar one or 2 for performance reasons from NCL/LBA I think we'll be 2 to stay with quite a lot of old 738's and 733's
Big earners like MAN, BHX and STN (maybe EDI) will attract the new aircraft first, which is understandable, obviously. More money and more utilisation will be important after such a large investment, the 733's and 1st gen 738's are paid for
I don't mind, it's quite entertaining watching them use every inch of runway at NCL on a warm, calm day
