£100k, Happyjack???? Someone saw you coming! You could do it for less than half that if you set your mind to it. As for the unemployment queue, everyone I know who stuck with it eventually reached the front, and most of them trained in the last downturn. For an eighteen-year-old who will then see relatively good earnings over a whole career and not have to sit looking at an office wall 9 to 5 over that time it is probably worth it. Having to actually work for a living is soul destroying. Aviation might have its dull times, but it has great compensation for that!
Integrated is more expensive and leaves you with less experience than modular, iranair. It is also very much directed to you being an airline FO, so tends to shut off other aviation careers which can be far more interesting if less remunerative. You can then earn the money in a big jet when you have family and responsibilities.
