Bond
I spent four years in DXB flying for a well known carrier even dough I joined as type rated i had 25,000$ bond in a period of three years.There was no actual salary deduction but had i left any time before those three years time frame they would have asked me to pay off the rest ....25,000$ for a four sim sessions including LPC and OCC .... so there is worst out there .... joining as a 23 years old guy with 300 h total and get to fly A320/321 with good career prospect is more then a good deal plus getting half of it back after ...the one might start look at the things differently
