Yes, without Delta mainline, American will be the only one offering mainline service. Although Mesaba, with our Avros, still provides mainline type service.
American is really strong out of here. In fact, for most of the summer, they were running three MD80s into HSV with one F100. Load factors are high for AA, as well as the yields. As the AA district manager once said, "Huntsville is a cash cow for AA." AAdvantage frequent flyers wouldn't be so forgiving if these flights we're downgraded to regional jets; Dallas is a much longer haul than Atlanta. These folks want their upgrades.
Ground employees here are not AA employees. The work is contracted out to ATS, and those poor guys make less than we do. So labor costs are not an issue out here. They really have no reason to pull mainline service, but stranger things have happened.
Continental was at one time blabbing about running a 737 on their Houston route out of Huntsville. This dosen't seem to be the case. In fact, they're losing a flight for the end of the year. Apparently, American is killing them in the westbound routes.
Nature forms us for ourselves, not for others; to be, not to seem.
