My flight from Dubai to Los Angeles was departing at 3PM, so a friend dropped me off at Terminal 3 at around 11:30AM, so I’d have plenty of time to review the lounge. Emirates has a separate drop-off area for first and business class passengers, which lets you skip the main part of the check-in hall altogether.
The Emirates premium check-in area is massive. First there are a bunch of red carpets for first class check-in, and then behind that are blue carpets for business class check-in.
After that I proceeded through immigration and passport control, which was relatively quick thanks to this checkpoint only being for premium passengers. Once through security I took the train to the A Concourse, which is Dubai Airport’s A380 concourse (though 777s depart from there as well, and not all A380s depart from that concourse).
