Bottom line is - don't be the guinea pig!
One of those guinea pigs would be me.
If all goes well, I will soon have my MPL with linetraining as part of the contract, and with a possibility for a two year bonding. (reduced salary, but still ok)
During the basic phase we had instructors from several European airlines and the local CAA, all convinced that the MPL route is the best route forward. I know it is a bit one-sided, but it shows that at least not all major airlines are anti MPL. But if the "common" perception out there is what is reflected in this forum, I hope pilots out there would be a bit more open-minded.
As for the ATPL, as long as you have the required hours, you do not need anything beyond a MPL.
Think I will dig myself a ditch now, waiting for the incomings...
