FlayinSpanner you say you are asking for help. What sort of help do you expect to receive? Some way of deceiving your parents into believing that their home would not be at risk if you fail to be able to repay the money? Dream on!
One of the things you have to learn in this world is that it owes you nothing. If you want something, you have to do the work to earn it. You say you've worked so hard to get where you are now - so what? Does that mean it's now time for someone else to pick up the bill? Dream on some more!
If you cannot get into CTC's scheme, or the other airline-assisted schemes available, then you will have to pay the bills yourself. It is possible, as plenty here can tell you. If you really can't envisage a way of earning enough to pay for your training without risking your parents' home, are you really up to this career?
As Farrell said, this is your dream, not theirs. If you want the dream to turn into reality, don't do it in a way that may destroy what they've worked for so you can get there.
