Just a few days after announcing a major route map expansion, Alaska Airlines is back with another network update. This time, however, it's all cuts.

The Seattle-based carrier filed plans over the weekend to drop two routes from its network and suspend another, as first seen in Cirium schedules and later confirmed by a carrier spokesperson.

Alaska will exit the San Diego-to-Cancun market and the Orange County, California-to-Bozeman, Montana, route, effective immediately. Both of these flights were originally supposed to return for the winter season, but Alaska told TPG that they are "removed ... from our schedules going forward."

Additionally, the airline has suspended service between Los Angeles and Bozeman. This route was also originally supposed to operate during the winter season, but it's now suspended indefinitely. Alaska is no longer selling tickets in this nonstop market, though the airline told TPG that these flights are "suspended," meaning that they will likely return in a future season.
