Thank You. I don't know how I forgot Houston. (It could have been when I was crossing out all the non-American airport I accidentally crossed off Houston)
Boy, if you consider that MIA and the West Palm Beach airport are 70 miles apart, then you'd have to say that Milwaukee, Gary and Rockford also serve Chicago. All have scheduled passenger service.
Yes, an airport in Ontario, California, 38 miles east of downtown LA. All major American airlines connect Ontario to one of their hubs, and they also have service to Guadalajara.
