NEVER ever ever ever ever ever ever ever pay more than a few quid up front. As long as you have YOUR cash... FTO's want it ... so keep it that way and stay in the driving/ flying seat and,... stay in control!
Take that from someone who got ripped off by a certain Florida FTO who's name can't be mentioned here. I did'nt lose any cash, but got a crap deal which would not have been the case if the money was in my wallet.
Escro accounts are the only way you can protect yourself, but if an FTO demands cash up front, ask yourself the question WHY?!!
DON'T...DON'T DO IT!!!!!
By the way, I don't know what Cabair's accounts department is like now, but when I was with them it was a disaster!! If it was'nt for the fact that I had NOT paid in advance I would have had a hell of a debate!
