Southwest Airlines has announced that it is cutting nearly 20 of its routes, including its nonstop service from Austin to San Francisco.

The cuts, which were released as part of Southwest’s most recent schedule update on Aug. 15, will go into effect in January. They're being made so that the airline can add more planes to routes with stronger demand, a Southwest spokesman told USA Today.

Three nonstop Dallas flights — to Oklahoma City, Jacksonville, Fla., and Sacramento, Calif. — will also be eliminated as of Jan. 6.

The announcement comes just weeks after the airline announced it will stop offering all service into Newark, New Jersey, starting Nov. 3.

Three airlines — United Airlines, Frontier and Alaska Airlines — will continue to offer nonstop service from Austin to San Francisco; Southwest will continue to offer one-stop service.
