Comfortable?! I haven't been to DXB for a little while but in response to some of the other comments, and the high aggregate grade around Comfort, I would say that it was a madhouse the times I've visited. You could say that's a good thing - great shopping, cleanliness etc for thousands, even in the early hours of the morning (what is 'morning' for those on all sorts of timezones passing through?) - but I have felt far more comfortable in other airports. Be prepared for queues and general human traffic. Still a good airport, though.
