I have been flying EK quite regularly since inception and whilst I've had the odd delay here and there, they have been pretty reliable for me. I do not count 30 minute push back delays as being that as long as I arrive within 20 minutes of the scheduled time. Its not the Shinkansen, you can't expect flights to run on the minute, there are other factors at play.
Lol you must work for Emirates, Zol, otherwise how can you possibly look at this issue in this way!
