I wouldn't say that so much about IAH. We have more international airlines then one might think. Besides, Continental has alot of flights for NYC.Geaux Tigers said:The big international airports in the US will always be the cities on the coasts. It just makes sense for airlines to only fly far enough to get passengers into the US and then let them change planes. That's why JFK, Boston, Miami, San Fransico, and LAX will always be busy international airports. Chicago is just in a great geographic location on the great circle map for airlines. Atlanta is as busy as it is because Delta practically routes every flight they have through Hartsfield. Same goes for Houston and Continental.
Look for DFW to really move up in the international passenger rankings when Qantas starts direct service to Sydney here in a few of years.
