I don't think I've been to a "bad" US airport (Mid Continent was as dull as though). For bad, try BOM or NBO (though people who've been Lagos, Kigali and Algiers tell me that these airports are really grim).

Imagine what someone who has only ever experienced dodgy African airports might think of LAX. Actually LAX might be a bad example because the really peeved M.... M.... M.... Members of the human race working at one of the Burger Kings there might ruin the experience for them.
