As Nutloose says. Plus another one:
-They ask you for the details, so it feels leggit.
-They send you all flight "details", so it feels leggit.
-Then they ask you to pay a fee for visum as the aircraft is in X and you will get it reimbursed.
-Oh and please pay for the ticket..
As you think you will receive $$$$$ for a short assignment you are willing to pay the relative low amount of $$...
You arrive: no aircraft, no nothing and you need to pay your own way back.
