whatver you do, don't pay.
if they are interested by you, they pay for you, you work, and take money from your salary.
now most airlines are just interested by your money, P2F then you are OUT!!! they lurk you with stories like you will get a job after line training.liars!
just show up in an airline and ask them if they can take money from your paycheck...
I can tell you, they will not talk with you any further! all they want is to fill their pocket with illegal p2f until crash happen!
