That pay might just about be an acceptable trade off if the lifestyle was great - but in flybe it isn't. The specific issues such as finishing on lates and starting on earlies, and the 108 day off fixation have already been mentioned by previous posters, and I agree with then completely.
Royston Vasey sums it up well: "So, in years to come when the family have grown up so fast you're wondering where the time went; and you're kids are overheard saying that Dad / Mum were 'always at work' you need to ask yourself....
Were all those six-on two-off, start on earlies and finish on lates really worth it."
I have been trying to get out for two years or so, but in the meantime flybe have severly limited my ability to support my children through crucial years - and I will never forgive them for that.
