BFS/BHD
I seem to remember that easyjet is a bigger operator and is the No 1 carrier out of belfast
I'd certainly be surprised as BHD-LHR is supposeldy BMI's most popular route
However in this age of yeild and revenue management popular does not equal profitable ( no matter what the rest of us think )
PS the upgrades for the 321 where paid by airbus under the terms of the operators lease
