Hi Ws/Paul
There are lots of good replies and i think the majority highlight the main requirement that you should have, determination.
I think academic qualifications are important however not essential, i like many friends, some of which are pilots, left school without A levels with very average GCSE's. At 17 completed PPL, embarked on the ATPL writtens which were a struggle, but, if you are prepared to lock yourself away for a year and give everything you've got and know that the chances are you will fail exams from time to time you will do it!
My academia has never been questioned by an airline. Another option for you if you are concerned is once you have completed your studies, maybe a flying instructor looking for a first airline job etc etc, you could undertake the masters course in aviation management or any similar qualification, it would always be something to prove your commitment and the fact that just because you don't have 15 A+ A levels you are intellectual! Bottom line go for it and sooner rather than later
Paul same advice, again i have a couple of mates in similar circumstances, it's a big move but with courage and determination and as long as both you and your partner are aware of the struggle, i'm sure you'll achieve your goals.
Any questions from either of you just PM me
