Southwest wants to create an international gateway at Hobby Airport. United doesn't like that. Its largest hub is at IAH, 30 miles away.
United just nuked thousands of local jobs and moved ops from Houston to the business-friendly, Obama-friendly climes of Chicago during the United/Continental merger. United management won't admit it, but I'll point out the obvious: The location of United's headquarters was determined by the occupant of the Oval Office. The Feds would never have approved the merger if the HQ had remained in Houston.
Now United is whining. They may pull international routes. I have no sympathy. Fares at IAH are the highest in the nation (read: fat profits for United) and Houstonians will benefit from the competition on international routes, particularly to Mexico and the Caribbean.
To reiterate, United cuts Houston jobs, gives us the highest airfares in the nation, then threatens service cuts if a competitor offers cheaper fares and thousands of new local jobs. Gosh, which side should I root for?
