I fly to/from Reagan to either Tampa or Orlando several times a year. Reagan is small and not much there, but it used to be a (relatively) quick and not too unpleasant airport if handled a certain way (i.e. Terminal C). Since the AA/US Airways merger, though — not so much!
Never had any problems in Tampa; it is usually fast and efficient. Other than security, Orlando is usually nice as well, although I have had more delays from there than Tampa.
I have had good experiences at Phoenix as well. No complaints! I do like walking though. And I have never had any problems at DFW, although maybe it was because I always had plenty of time.
But I agree with the posters who said they’d rather pay more to avoid Miami — what a mess! And as far as Atlanta, well, isn’t it true that when somebody dies and goes to hell, on the way they have to change planes in Atlanta?
I was never impressed with Atlanta.
My worst experiences were always at Minneapolis-St. Paul International. I was snowed in there on my way back to Basic after Christmas Exodus, ate a hotdog at the USO and got violently ill for the next 24 hours. In fact, I didn’t eat a thing for three days after I got back to Basic. Gone through MSP 3-4 times...NEVER had a good experience. That one in the Army was the worst.
