I flew to Chile on Continental. They happened to have the best prices AND I happened to have a boatload of frequent flier miles with them.

Continental has "George Bush" airport in Houston as their hub. It's a bunch of separate buildings all interconnected by long hallways. It's probably a mile from one side of the complex to the other. I tried pacing it off several times, but I'd always get distracted.

Wear a long-sleeved shirt if you need to transfer through here. It's cold. I talked to some Texans who admit that lots of commercial establishments over-aircondition in Texas. Apparently it's the Texas way. I've had to buy two "souvenir" shirts in this airport just to keep warm.
