Envar,
1400 in the senority list ? Noop...You will be placed on B777 's senority list...with all the expected jets coming...soon you will have your LHS back ! Benefits are good..city is definitely better than yours right now...flights are different too and we(drivers) need that kind of chalenges to keep us alive. I was in your situation few months ago..made my decision...EK is better than my current job..I was fed up of small airlines.
Can I regret latter ? maybe but I know many guys who are very happy there and usually they don't come here to state it !
