It's really annoying when you enter the airport to wait at long lines. It's very possible that you miss your connecting flight if your layover is less than 70-80 minutes.
I don't know about t3 but ,t1 is pretty wack. Limited food options.... Slightly haphazard...and the airport information people are haughty emiratis who you can tell have no interest in helping you.
There's a huge people-traffic-jam at the way to the terminal 3 because the escalators isn't working. And there's also a huge people at the security to the terminal 3. Too busy airport, uncomfortable
SUCKS AIRPORT and "Winner of the Best Airport in the Middle East 2012" hello ! Are u crazy ? have u been to Dubai apt ? crowded, lack of service, small, nothing interesting inside, arogan staff,bravo
Overcrowded airport not really adjusted to the traffic increase witch took place in the last years . May be comfortable for Ethidad Business Class passengers but bad for Economy passengers .
I found the airoport cousy with free WIFI however airportstaff is disorganised. They sent my laguage to the wrong place transiting to China even after I have been to the transfers office.
