I have the prospectus in front of me now, and no-where on it does it give a figure for a salary, in fact it actually says 'the salries may be less than the market rates apllicable to non sponsored employees' - meaning it is!
You have to shell out 12000 plus VAT for the training and also sign for a 15000 bond with BE should you fail to complete the 39 month employment with them.
It says that the 18-24 month period at cabair is 'work experience'. I don't know how many hours a day you will work, but my guess is they will have you there all week and maybe a saturday or sunday??? not too sure on that, i have a couple of friends who work down there, they said that when KLM UK did this quite a few dropped out as they could not afford to live down there!
Hope this helps you out, good luck if you enter.
