As posted before, the accelerated command is out of the picture. That is if the rules are being followed. There are way to many guys with over 3 years who should have the priority. Even if you join on the Boeing fleet, by the time you get to your accelerated time (18 months) there will be quite a lot of colleagues ahead of you.
If EK plays it by the rules, forget about the accelerated stuff and expect a command between 4 and 5 years if you join now. The longer you wait, the longer the wait will be..
Then again:
EK is not keeping to the policies. A few accelerated guys just bypassed a lot of 3 year guys with NO valid reason. So to answer your question:
Accelerated is 18 months in the company, 8000hrs of which 2000 in command of a +55ton Jet.
I heard recently from a friend on the Boeing fleet that they won't use the 55ton criterium anymore, so if you were on a regional jet, you might even get an accelerated command.
Conclussion: Don't come here for a fast command!!! EK changes the rules so often, and when changed, they will follow a different set of rules anyhow, so fast upgrading is becoming a bit of a lotery. If you have your mind set on 5 years, you won't be far of the 'normal' scenario. Should you get an earlier upgrade: lucky you! But in case it doesn't happen, that won't be a thing you are unhappy about. (And there is plenty more tho b1tch and moan about)
