That would be the best course of action if management took a firm stance and decided to actually take responsibly to ensure pilots were properly trained before getting in the coughpit. Unfortunately from what you have told me this isn't the case for quite a few airlines. I'm quite ignorant about the quality of each airlines pilots, if you asked me honestly I wouldn't be able to tell you who I thought had the best quality pilots. From what I have read Qantas and BA are somewhere near the top of the food chain, after that I wouldn't have a clue. I understand you are not in a position to start reeling off names, however if someone has an informed opinion I would be happy to receive a PM about it. I don't know whether to laugh or actually believe the good old "If it ain't Boeing I'm not going"....Command training in many airlines is measured in weeks...if you lower the goal posts enough, nobody fails. So, the answer to your question would have to be 'easier'. Bear in mind, this is not all airlines, but I'm sure the obvious ones will jump out at you.
The problem is that within a short period of time, and probably in some airlines already, the number of experienced people is far outweighed by the new brigade. Their knowledge and standards become the average, so they don't even realise how low the bar is.
Why not train them before they get into the seat? On the job training, in aircraft, assumes that nothing happens in the early days. Bad things can happen on any flight.
All I can really judge an airline on is accidents and incidents, but like you say - who knows how many "near misses" there actually are that we never know about. I have QF17/18 on my travel itinerary next month, looking forward to flying with Qantas again on the 747 - it's been a long time and some of my fondest childhood memories are at the airport looking at the big 747's and wishing that was the plane we would be getting on, unfortunately it was always the smaller 767's !!!
