As is the case with oil, gasoline and other refined fuels, in aviation what happens in Houston does not stay in Houston. United’s hub at Bush Intercontinental Airport typically operates 483 flights day that carry about 42,300 people a day. Southwest, meanwhile, operates 152 flights a day from Houston Hobby Airport that carry about 20,000 people a day. Hobby Airport, one of the three original Texas airports Southwest served when it launched business in 1971, still ranks as seventh-busiest of the 49 airports Southwest serves. But this morning FAA and airport officials extended the airport’s closure at least through noon on Thursday.
