However I dont have £80,000 spare to pay for all my own training,
You have 2 options.
1 - Get into a flight school, something like CTC or Oxford Aviation Academy, there are plenty of others - this is called integrated training(you study full time and do everything with them - a PPL is not required), keep in mind this will cost you around the £70,000 mark.
Therefore Paddy88 has ONE option - as Option 1 is not an option!
