Sounds like a marvellous idea. Get yourself a financial makeover by professionals, plus a load of publicity to show "here I am, I'm a decent sort worthy of an airline job".
I'm pretty fortunate in that having got a CPL/IR and a FI(R) I'm 'only' £5200 in debt (oh, plus £1200 on a student loan and £3K still to pay on my car), so probably not the best person for the show. Someone with a £50K debt and a remortgage would make for MUCH better TV!!!
Good on you, BBC for doing the show, and whichever lucky bugger it is who gets to go on the show.
