First misread the BA part, however that was never going to be majority of pilots recruitment way in the past, as there was huge competition to get in, similar as the air force.
Paying to get your rating seems to be the way forward anyway, unfortunate but true. Paying to fly, is not, look and search some of the threads of the people who have done it, and see what they experience was.
Anyway you are going to need a lot more than £60.000 if that is the way you want to go, you hour building, CPL, ME, MEIR + MCC will at least cost you close to £40.000 - £50.000 if you do it modular, forget integrated, that will be more.
I am not saying never to consider it if the situation permits, however you should try other ways first, if you do not succeed the self improvement way, get a type rating and try to get yourself a job in middle east or far east, I have heard this has worked for some, without paying for line training.
Of course depends on age etc., but you wanted advice, what you do if you blow £80.000 on training + line training, 500 hours will give you something, but probably not enough in todays market to even get a sniff of a job that will justify that kind of investment.
Line training is not just the TR + 300/500 hours you pay, the company does not pay anything for your expenses, you pay your own hotel, your own expenses while you are their slave, for however long they need you. I have heard pilots on these schemes not even being able to complete the 500 hours in 12 months, they can stretch it out as long as they need you, because you have paid them, and will you walk away from the investment you have made for line training.
I am not a massive fan of Ryan Air, but they do give newbies a chance, so even though you need to pay for your TR, you will most likely have a job for as many years as you need or want.
You have not received many responses from many experienced PPRUNES, because this topic has been discussed to death.
I do wish you and everyone else the best of luck in their pursuit of a flying career, regardless of how you do it. Someone mention here that P2F is an accident waiting to happen, can't really agree in that, they have to be highly motivated to risk that much money with no security of any return. And other low hour pilots have all been flying in the past and present for companies as BA, Lufthansa and Ryan Air, so it is not an unusual system to have love houred FO's, however paying for it is the taboo, and when things does change and pick up, you might be stuck in a P2F contract in Indonesia or Marocco, unable to get of this "contract" while others get hired.
It is a lottery!
