To correct a few points.
You can apply for Emirates with 2500 hours on a medium sized jet.
Cathay Pacific Second Officer program requires no previous airline experience.
And what about the 4000 hours TT?
For example, I have 2500-2600 hours on the 737 or A320 but less than 3000 hours TT. Still eligible for Emirates even despite the fact I am short of more than 1000 hours TT?
