Let me tell you the truth about B747 HZ-AIU this machine most of the time is grounded so if you looking at flying cargo you will be on ground most of the time, this aircraft is good from the maintenance perspective but had a veru bad luck i flew this machine all over the word as a flying spanne/flight mechanic and i know this aircraft inside out.
Saudia as an employer is very gooooooood & veryyyyyyyy generous you will not have a problem there beside what you should expect as an expat any where in the world people generally are friendly & helpful i enjoyed my stay over there for 12 short years very much and still regeretting my resignation.
