I would say at your age, Bug, listen to the advice of cldrvr!
You will not regret it, believe me! Go modular, take your time, FIC, maybe even go and instruct in US or UK, there are jobs available this route, it might take time, but the secret is not what you know, it is who you know!
Going CTC / OAA, today unless the BA program is hopeless!
In 1992, when I was intending to go commercial, I also wore glasses, I was outside my CAA's requirement, +/- 3, and my only option was to go to US and gain experience, and hope they would give me medical based on this!
15 years later, the requirements had changed, now they are +/- 5, and I was suddenly within requirements, and I got my class 1 medical, it just shows, patience does work!
I got my first aviation job last year, at the age of 43, so it does work!
The money you will spend with CTC, will not give you any guarantees of anything, it is very likely that you will still need to pay for a TR at a later stage, so that amount you expect will rise, and unless your parents have unlimited funds, so will your needs.
With CTC / OAA expect at least to spend £120.000 - £150.000 - incl. TR, living expenses and maintaining your licence!
Modular you will by unlucky if you spend half of the £120.000, probably close to £40.000, than FIC - working getting experience / contacts - and if lucky you might not even need to pay for your TR!
At your age, why the heck is your main ambition to get into Airbus or Boeing first, when you arrive there, flying will be much less fun than it will be if you follow this route as suggested!
The thing, you can also work during the time you train, so your debts will be much less!
