Your training experience sounds pretty grim. But does your move mean that the training is pretty standard across airlines? IATA defined perhaps? In any case, are you looking to be based in one of London's airports? Good luck!
I think Ryanair has definitely got a more strict training system. I have friends that work for British Airlines, Easyjet, Thomas cook etc and they think I’m exaggerating when I tell them people’s hair was falling out in my class from the stress and lack of sleep. But that’s Ryanair’s way of getting your money and then getting rid of the weak. The training alone is a huge million pound business. I’d like to be based in either Bournemouth or London Gatwick though so hopefully will be someday.
