Using e-ticket machines can save you a considerable amount of time, though, espeically if you can't use the elite check-in lines. You will need only a major credit card, and the machine will retrieve your details. Very easy, like using an ATM.
If you have bags to check, make sure you use an e-ticket checkin machine in what looks like the regular ticketing desk -- i.e., an agent behind the desk, and a luggage scale next to the machine.
There are several banks of these machines, typically located on the ticketing level along the exterior wall to the roadway.
