United Airlines Holdings Inc said on Tuesday it was temporarily, but significantly, reducing daily flying in and out of Los Angeles and San Francisco airports to better match demand that has dropped due to the new coronavirus.

Starting on April 12, United will operate 13 daily flights from LAX to six destinations, down from 33 flights to 19 destinations previously, and 50 from SFO to 37 destinations, down from 65 flights to 40 destinations previously, Chief Operations Officer Greg Hart said.

In other airline news, Southwest Airlines said it would publish this week a new flight schedule for June 6 to June 27 with overall flight activity dropping by about 50% while taking into account "different phases of the recovery anticipated ahead."

"We’re building plans that reflect forecasts both for diminished demand and potential travel in late spring and summer," Southwest Chief Revenue Officer Andrew Watterson said in a memo to employees.
