Reagan -- Coolest approach ever. If you're lucky, they'll bring you down the Potomac from the northwest in the evening and you'll see the mall and the monuments all lit up just before you land, and you think you're going to land in the water. Makes a bit of patriotism swell up inside.
KCI -- Greatest airport for dropping or picking people up. "Drive up gates" were revolutionary at the time...unfortunately, with the advent of the hub system it lost competitiveness, but I personally think it's aged pretty well.
KC Downtown -- Never flown in there myself, but an acquaintance who used to fly for TWA back in the day says that when you approached from the south in the evening, you could see people eating dinner in their Quality Hill apartments.
Norfolk -- Worst gawdawful walk ever, and the TWA gate was at the very very end, so it was longer to walk than any other.
Lambert St. Louis -- Pits of hell. Trying to make a TWA connection in there was horrendous. Crappy airport, all the way around.
BWI -- Under construction when I was there, which made it a mess. Not very impressed.
Toronto -- Don't remember much.
Seattle -- Seemed like a pretty cool, contemporary airport.
Minneapolis -- See Seattle.
DFW -- Not bad for as big as Dallas is.
Dallas Love -- Nice option there in Dallas.
Charlotte -- Don't remember it very well...think it was contemporary.
Sky Harbor -- Not bad.
Dulles -- Meh. People movers were kinda cool as a kid, though.
Richmond -- Don't remember much.
Midway -- Meh.
LAX -- Love seeing the cloud of smog during the descent.
Orlando -- Didn't pay much attention to the airport--I was focused on getting to Disneyworld.
Atlanta -- Don't remember much.
Waco -- Two gates, automatic sliding doors.
Ft. Smith -- See Waco.
Little Rock -- Meh.
Honolulu -- Don't remember.
kuaui -- Don't remember.
San Diego -- Seemed okay when I was there.
Law Vegas -- Gotta love slot machines right outside the gates.
