When you're used to modern, well-designed airports at SFO and SJC, this place can be frustrating, especially for first-timers. It has an annoying lack of directions/signs and confusing roads. How am I supposed to know the difference between Terminal 1 and Terminal 2 if no airlines are listed? (hint: Terminal 1 looks like it has pretty much every domestic airline)
Also, passenger pickup was insane on an otherwise normal Saturday evening, and I expect it to be even worse this Saturday (New Year's Eve). However, the security checkpoint lines on both weekdays that I've been here are spectacularly short. That makes up for the other shortcomings easily.
