would therefore assume that the £60,000 would be paid back to you over a certain period once you have finished training?

If you can self-finance you simply cut the bank out of the equation and give the 60 grand straight to CTC. You don't get it back, believe me! What you will do is save yourself around 24k worth of interest payments on a bank loan. What the airline pays you when you join depends entirely where you end up. At easyjet you will simply earn an F/O salary without having to give the bank a grand of it every month.
You won't be bonded, you can go where you like. CTC call it a "bond", which is a load of
, you pay 60k for your training, you are under no obligation to stay at any airline for any length of time.
