You must be inundated with applications from highly experienced Airbus and Boeing pilots then, probably so many that you don't need to run a partial sponsorship course...
Perhaps more heavy time/rotary/FJ ex RAF peeps.
Bit harsh though LSM. The Dash is better than shelf stacking or bar work when leaving Oxford/CTC/FTE etc etc. many opt just for that. Others really give it a shot and hold out by working as performance engineers in a flight ops department and put what they learnt to use. Then those with cash or equity to burn go for P2F TRs. It is hard o say what the right route is. Frankly it is all personal choice.
I know of P2F Ryan boys and gals in BA/EK after 4/5 years and BE gals and boys in MON/FZ/BA/EZY/LS after 4/5 years. Some have paid for TRs, some have not. Some have 4 TRs some have 1 or 2. But not one person I know if has paid for more than one, if any.
The makings of your career are in your hands only and no one else's.
For those interested in the three schools mentioned, they really are all the same these days. Very very little between them. Just do lots of research and pick the one best for you.
