it is called the Multi-Crew Pilots License as I will be trained from day one to fly in an airline environment with my Captain
And what will happen when a MPL captain will be incapacitated?
Passengers are paying their ticket to be flown by professional pilots, not to pay for student pilots' flying lessons. I'm not sure so many people would agree to make concessions on that side. Remember the LH incident with the 250h cadet... that was a very close call. I understand it is exciting for young people to immediately start flying a shiny airbus, that doesn't mean it is the best way...
