MOR / notac, I understand your anger but do recognise that things do change over time.
There could be any number of reasons why the 737 trial was right at the time but perhaps isn't the right method for the long-term future. It could be that the markets (particularly at BHX) into which Flybe entered are too competitive and yields are too low to make any money. It could be that any new potential owner of Flybe doesn't like the idea of playing the easyJets and Ryanairs at their own game with 737-size aircraft, and instead wants the company to focus on regional routes with regional aircraft.
Just because things have changed from then to now doesn't necessarily mean that someone was lying in the first place! At the end of the day, the company's primary objective is not to provide its pilots with a nice type rating. I presume its priorities are much like any other airline - operate safely and make a profit. If you can get a 737 or A320 type rating into the bargain, then good for you. If not, venting your spleen on here isn't going to change that either.
