IVER..
After you have your wide body type stamped on your license and your command hours there is not much here to make you stick around if you come from a safe place to live. After you gain the above the money is simply not enough. The seniority has only a tiny impact. EK has a rotating seniority system and they now have restrictions on how many days off in a row you can bid for when in the top bid groups and manually insert trips on your roster to maximize the work you will do, so commuting is not an option. You will earn slightly more more money with seniority but you will eventually view this as not enough. Time will tell.
