Whats that got to do with the flying side of things!
Nothing if you are an anorak who just wants to fly aircraft, sorry I thought this was a discussion about making a career selection.
The option of leaving if you do not like it is not available to everyone but having said that the BMI pilot workforce is mainly composed those who have failed to get into BA and Virgin, those who are about to apply and those who are about to retire. The first mentioned can usually be recognised by making statements like, " if you do not like it you can always leave".
