American Airlines is removing the grounded 737 Max from its schedule into December, but the airline still plans to fly the plane during the busy holiday travel season.

American on Sunday extended Max flight cancellations through Dec. 3, a move it said impacts about 140 daily flights. The plane, which was grounded in March following two fatal crashes in less than five months, had been out of its schedule through Nov. 2.

Travelers whose flights are affected will be rebooked on other flights or can request a refund.

Like United, American stopped short of removing the plane from its schedule through the holidays. Southwest Airlines took that step in July, removing the plane from its schedule through Jan. 5.

"American Airlines remains confident that impending software updates to the Boeing 737 MAX, along with the new training elements Boeing is developing in coordination with our union partners, will lead to recertification of the aircraft this year,'' American said in a statement.

American had 24 Max 8s in its fleet at the time of the grounding.
