it's all the same with ryanair and the b738, and believe me or not, that's the way it is. Ask the trainers at ryanair, easyjet, ctc what they think about it... I don't think they are scared of signing off hundreds of 150 total hours cheap cadets. And it doesn't make any problem neither for the insurance to let those inexperienced guys.
Remember, in 99.9999999% of the whole flight the autopilot and computers do much better than you.
