Yep this is the same boat I'm in at the moment,had my HSBC interview(preliminary) which went well I thought along with my parents.I myself am 22 and looking at borrowing to follow the dream.Like said though big gamble n job prospects at the end.Though I'd rather give it a damn good try than be around 10-15 years later and regret not trying.
I currently work at Belfast City Airport and now have a number of friendly contacts with persons amongst FlyBe and BMI.Ideally I'd love to be based out of EGAC!!
