IFRKING
BAFPP requires you deposit an £84000 bond. This is paid in installments to your chosen flight training school. BUT, this can be borrowed from BBVA "a London based Spanish bank that will accept applications for the funding of pilot training".
Although BA pay successful cadets this bond back (£1000 per month for 7 years, once on BA's payroll), they do not pay you back any interest you have incurred during the loan period.
