The last thing I have to say on the matter is with regard to this:
if your flying a a319 every day I wouldn't care about the money or conditions because I just love flying.
Most pilots will understand how you feel. It is however important to remember that at the end of the day this is a JOB. This is where it can become risky. I think you said your parents would lend you the money. Maybe your family is quite fortunate and finding £100k+ is not a problem, but if this money comes from a mortgage then you are risking your families home.
You are aware that the loan repayments kick in on the 25th month, have you thought of 2 likely scenarios?
1. You enter the hold pool (at a time roughly when the MPL guys will be going on line) and you may have a 2 year wait. If it's the BBVA loan then I believe you can take a reduced repayment for 2 years, but we are still talking £700/month and afterwards if the wait is longer (don't assume its not going to be longer) it goes up to £~1000+/month. How will you pay this back without work?
2. You come out of training straight into Easyjet on a 6 month flex contract. You get paid in the region of £1200/month for these 6 months which will just about cover your loan. after 6 months Easyjet don't require your services and you are out. CTC have indeed placed you but now you are unemployed and are looking at soon paying back £1000+/month.
It's easy to try to forget about it and assume it will all work out for you, and it might. The problem is that it also might not and then what do you do about your parents house?
It's just opinions, advice and food for thought but it's worth having a good think about.
