American Airlines Group Inc said on Friday it is extending cancellations of Boeing Co 737 MAX flights through March 4, 2020, mirroring an earlier announcement by Southwest Airlines.

American had previously canceled about 140 flights a day through Jan. 15 and now expects a return to service on March 5.

Southwest said on Friday it would remove Boeing 737 MAX jets from its schedule until March 6, 2020, just shy of the one-year anniversary of an Ethiopian Airlines crash of the jet that led to a worldwide grounding.
