The facility in Abu Dhabi is partially being funded by the US taxpayer (something like 15%). However, the biggest gripe is that since no US carrier services the affected routes, that basically the US government is pushing business away from US carriers and to a foreign one. Even if they didn't use a dime of taxpayer money, it still hurts US commerce.
Building a second international facility in a US city is nothing like this. Plenty of US cities have multiple international gateways (Miami, NYC, LA, Chicago, etc), especially as metroplexes grow. You referring to Houston by saying, "... in a city that doesn't need another..." is just a red herring. The people who actually live in Houston would love increased international opportunities and competition. This HOU growth will allow international competition between US carriers, and spur more growth of US flying in the Houston area. The fact that it cuts into Unical's virtual international monopoly in Houston bears no relation, and Unical's (and your) pathetic argument against Southwest flying international out of HOU is just an attempt to keep your monopoly at the expense of the flying public.
Hey, your airline is welcome to fly out of Hobby if it wants to, Flop. It was also welcome to expand internationally out of Hobby. The big difference was, that if it was Unical who offered to build a facility at HOU, we wouldn't have whined to high heaven about it. We probably would have just smiled, then leased the available gate that you paid for, and when our business grew, we would have expanded the facility into whatever size we needed. And that's the main difference between your airline and mine, Flop: we compete by putting our product against other airlines', and servicing the customers who like us better. You "compete" by attempting to hobble and obstruct other airlines, and service the customers who use you because they have no other choice.
