United Airlines (UAL) - Get Report  announced Friday it was extending the cancellation of Boeing 737 MAX flights until March 4, mostly matching the return date scheduled by peers American Airlines (AAL) - Get Report and Southwest Airlines (LUV) - Get Report

The return date comes about a year after regulators issued a safety ban on the jet following two crashes in Indonesia and Ethiopia. 

"We are continuing to work through the schedule to try and swap and upgauge aircraft to mitigate the disruption caused by the grounding of the MAX," United said in a statement.

United previously said it would cancel 737 MAX flights through early January, though its new timeline could still change depending on the timing of the Federal Aviation Administration' approval of Boeing's repairs to the plane.

Boeing said Monday the FAA could approve the software fixes it has made to the plane as soon as December and the agency could also approve fixes to its new pilot training program in January. 

A week ago, Southwest, the U.S. carrier with the largest fleet of the Boeing (BA) - Get Report  737 MAX, said it was extending the removal of the beleaguered plane from its flight schedule to March 5 from Feb. 8.

The company changed its mind due to "continued uncertainty around the timing of MAX return to service," according to Southwest's regulatory filing.

Southwest said that as of Sept. 30, the operational leases for commitments totaling $533 million for 16 737 MAX jets had not commenced. The company has 34 total MAX airplanes in its fleet.

American Airlines also has a March 4 return date for Boeing. 

Boeing shares rose 1.1% on Friday to $371.49.
