Odd question, I know. I fly a lot, so I spend a lot of time in airports.
I'm particularly fond of Chicago O'Hare [ORD]. Plenty of food and the walkways between terminals are fun.
I also enjoy Long Beach, CA [LGB]. It's super tiny, you just walk onto the tarmac. There's no baggage claim. No jetways. It's quaint.

LAX is my hometown. I like the architecture, but it's nothing special inside. Sea-Tac is kind of a pain because you have to take a train to your terminals, and they get crowded. My favorite was somewhere in Chicago.
