With all the emotion here, it's easy to miss the salient facts.
Most BA Connect pilots are moving on because they have found a better offer elsewhere, as has evidently quite a few Flybe pilots. Is that so hard to understand? Those of us in Bristol were pushed into it by having the rug pulled from under our feet, but it's still the same principal - you look at your options & hopefully pick the best.
My option with Flybe was to relocate my family and move from a jet to a turboprop. My alternative was to stay put and fly for easyJet. Simple decision, nothing to do with company management, engineering, T&Cs, rostering agreements or even money.
