Chinooker,
All sounds very plausible. This is the ideal time for BA to take advantage of the slow down, and renew the fleet NOW when we really need more fuel efficient aircraft. If other companies are cancelling or delaying orders, this is the ideal opportunity for us to pounce.
Just one minor detail regarding the A321's...
If they are ex-GB Airways they will come from EZY;
Ex-BMED from BMI...
Will be very sad to the B747-436 go...
From those of us in the cabin, this aircraft is a dream to work on. Beats the other 2 aircraft in the WW fleet hands down.
