I like the smaller airports. Being able to get from the car to the gate w/o having to pack a lunch after living in ATL for so long is really desirable. SNA and the small airports in FL rock.
I used to fly into HHH at least once a month before Eastern went under. They had an airport bird, cat and dog. My pilot also worked at the car rental counter. They had a handheld metal detector. It was like "Wings" ;) They'd also hold the plane for you if you were running late!
I like LAS because of the slot machines - I never minded waiting for a flight
I like KOA because the flight in and out is so gorgeous.
I don't like ORD, ATL, DFW - too big.
