There's this thing called a scope agreement so even if bmi could make a fortune by operating a 146 on a route (highly unlikely) they can't. You can thank BALPA for that one. If someone thinks they can set up and manage an airline then I wish them the best of luck. If you've got enough money to finance it yourself you don't need to work anyway. If you can convince someone else to then you've got one hell of a business plan and nothing to lose, so go for it!
