Wouldn't let age put anyone off. There are plenty of applicants at my flight school who are balding, grey hairs or both! The majority of younger cadets but the have degrees and/or previous RAF experience. If given a choice between all three schools I would go with Jerez based on the location and current fleet expansion - just because you haven't got in on the first go don't just give up. Took me nine go's to get onto an airline scheme!
