Chec Tunset,
There is nothing behind the fact BFS is last to get the bus in the EZY network. Infact if they could accelerate orders from Airbus they would base the bus at BFS. Just not enough A/C to go around.
The 737's last of which only delivered at the end of '04' have alot of life in them (less can be said for the likes of Jet2's steam driven types some of which unlike ezy's new models look abit scruffy aswell) and they will to be around at BFS for another 2 years.
There will be opportunities as LTN phases in the bus for 737's to be transfered to BFS and expansion will happen. A company expanding at the rate of EZY needs A/C and that is what is slowing expansion nothing else.
