I reckon aviation is going the same way that manufacturing has gone; that is to say that aggressively reducing costs is seen as the only way forward.
This whole flying game relies on pilot subsidy, all MOL has done make the subsidy even greater from pilots to Ryanair - hes just doing whats right for his business
He will get away with it as long as fATPL supply exceeds demand i.e. forever
This trend for pilots to pay all their training costs has been made
possible by the low-interest rates that we pay (AT THE MOMENT)
If interest rates rise then he may have a problem - but that will probably coincide with a slowdown in demand anyway
