Get a job post degree and save some of the money towards your training (whatever route you take) then go half and half cash and loan (you need the financial commitment to help with the motivation)
Don't do what I did, which is wait until I earned every penny and then start, it meant I didn't start until I was 32 (at Oxford), I aced the course (high first time pass marks in the exams and a first time IR with 3.5 hrs seneca time to spare). None of that matters when you're 35 and looking for your first airline job in a recession. Everyone of my class mates now has a job, some better then me, most not as good but they avoided age discrimination.
p.s. all but 2 of them had to pay £25K-£35K for their job, add this into your budget.
But for every one of 'me' there's probably 15 twenty-something first officers with £100K debt, so it kinda works but you start off life with a "mortgage" but no house, i think that's a good thing?
p.p.s. Oxford don't discriminate, just show them the money and you're the man.
