Alive, get real. Etihad are not going to look at a cadet with 300 on type neither are Qatar. I have no idea about China Southern but I'd imagine, in any case, they are only interested in taking Captains not FO's. Your figure of predicted earnings on the A320 are staggeringly unrealistic. Believe me I know. The A320 is stated to be the "golden type rating". It speak volumes that the only jobs available with this golden type rating right now are in the Far East. Fine if you want to live out there, miles from family and friends but many don't. Of course if you want to stay in "Europe" you may fancy earning less than a bin man's salary to fly max hours at Wizz Air and even then their recruitment is about to stop for the summer. Eastern Europe is also not the most pleasant place to live and is now firmly in the sights of the Russians.
The market is astonishingly bad right now even on the A320 and even with a so-called "economic recovery" going on.
