not sure how the Bacon King of 9 years ago forgot two airports:
1. London Heathrow, I visited it literally on the same trip as Frankfurt and Amsterdam
2. New Orleans - which was and is literally my second most visited airport after Atlanta! While attending Tulane, I made the flight between ATL and MSY probably four different times - about as often as I made the trip on Amtrak's Southern Crescent line. (of course once I moved off-campus to live in my frat house I finally had somewhere to park my car for free, after that I mostly just drove between home and school)
