Please be aware of one small fact when attending a roadshow, the presenters will tel you how things are now, i.e. 4 1/2 to 5 years to command is what is happening now. There is accommodation available now. EK is expanding rapidly now.
Once you get here, you will see that this is a very fluid environment, things that were said at the roadshow and during your interview were never meant as predictors of your career, merely things that were happening then.
The guys who are getting their commands at 5 years now, were expecting commands at 3 years. There are a number of pilots who were told all about Accelerated Command, being 18 months, who are now sitting in the queue for their 5-7 year slot.
There are those guys who arrived 2 years ago, who spent a year in temporary accommodation.
Ask your friends about how quickly things change here, and factor that into your decision making.
Having said the above, if the world is entering a growth phase, there are worse places to be.
