A hub and major connection point for US Airways and Southwest Airlines, if flying any other airline then you will likely face less delays and cancellations due to not being their hub
Many have complained about lack of outlets to recharge your phone/laptop, but I found no waiting for barstool/counter space at Southwest plug-in stations near gates D1-8, with great view of runways.
If you're using the light rail system - skip the rental car shacks, you get double taxed by the airport. ZipCar all around ASU - and no need if you're hitting downtown Tempe.
No matter what airline your fly, make sure you're at the gate 45 minutes to an hour prior to departure. Doors close 10 minutes prior to departure. Airplanes don't wait for you, YOU wait for airplanes.
A strange layout. small little off shots of gates and long stretches that require a hike or if you are lucky to find a cart. Look for your connecting flight carefully --waste no time in getting to y
Between planes do not stop to rest between gates A and B between flights. US Airways closed the gate in my face 9 minutes before takeoff. If you are reading this you probably missed your connection.
