Continental, it wasn't from Love Field to Intercontinental, it was from Houston Hobby to Houston Intercontinental. It was origianlly a DC-9-10 that ran the route, and eventually the "Houston Proud Express" was replaced with COEX turboprops. CO shut down Hobby completely after 9-11. At one time, CO had flights from HOU to EWR, CLE, IAH and LAX. Now, the only other airport served by CO is COEX flights from IAH to Ellington Field (EFD).
