why not?
come on guys, i think the 747 cargo or its variant has been around a looooooooooong time and will continue to do so. a licence with type endorsement should be good for the next 15 years at least. well maybe not with SQ.
yes, the pay is low compared to the mother company but where else in the world do you get a rating without climbing the rungs of seniority?
BUT if you are type rated, i would really like to know why you signed on.
