Connected the most out of St. Louis (TWA), Miami (AA), JFK (TWA/AA/B6) and Chicago (AA)
Been to Boston Logan Airport the most.. you probably know. Orlando, Miami and St. Louis are a close 2/3/4.
International Airports I have been the most to on seperate vacations: Aruba (8), Cancun (6), Dusseldorf (2) and London's Heathrow (2)...
Best airports on that list I have been to: Zurich (Most Modern) ... Beijing (Most impressive) ... Miami (Cleanest).
Worst Airports: New York JFK and LGA (Do I even have to explain?) ... Aruba (So Confusing, and the recheck process annoys me) ... Boston (Traffic from 128 and route 3 is torturous, best to take the pike in, nonetheless Terminals B and E are pretty cool)
Hopefully soon to add Madeira and San Francisco to that list soon.
