sorry ....but just got another option for you to think about:
Spend 5 to 10K become an accountant - your earning capability will be 45 - 80K in London, City.
With more experience - it will increase further.
Against spend 45 - 80K to gain an ATPL - your earning capability will be 25 - 35K initially... and that is if you are lucky to find a job.....
So if you do have an accounting and finance degree - do the pros and cons! ;-)
