  1. Although Atlanta remains in no. 1 spot, Beijing and Dubai are nipping at Atlanta’s feet! Moreover, it’s interesting that the bulk of Atlanta’s arrivals and departures come from domestic, and not foreign, flights. It’s also interesting that Dubai has grown so quickly that it now eclipses LAX!

    I’m surprised u didn’t mention Bush International Airport in Houston Texas to be among the top 20 businesses whether it’s domestic and international airports. I’m a flighattendant 14 years with British Airways and always fly out of Bush. Bush is my home hub because I married an American.I’m originally from Oxford England
