AS has never seemed to have more than a bare-bones interest in Houston, and I’ve never understood why. It’s the fourth largest city in the country and a global business and energy center, and has strong business and tourist ties to both the west coast and especially Alaska. Seems they could find a decent niche, but have kept it at the usual out-and-back daytime service supplemented with a less-than-daily seasonal red eye turn from SEA only. Doesn’t make much sense to me.
