I would think very carefully before joining Air Arabia and Air Macau. I have not heard a single good thing about the airlines. There are threads about both companies here on Pprune.
EK and EY would be the best in my opinion. I know one guy who is in the holding pool for EK and have been there for 7 months, so it is quite a wait.
GF is down sizing and only hired 2 guys from what I have heard.
If you are also interested in Asia look at Dragonair, Asiana, JetStar, VietJet or Citilink. Joining either VietJet or Citilink might be very quick since they are desperate for FOs.
