United Airlines extends cancellations of Boeing 737 Max until early November

United Airlines announced on Friday that it would extend its strandings on the Boeing 737 Max until Nov. 3, with 2,100 cancellations in September and 2,900 in October.

United, which owns 14 Max aircraft in its fleet, had already removed the aircraft from its schedule until August 3rd.

"We continue to work on the schedule to try to trade and over-equip aircraft to mitigate the disruption caused by the grounding of the MAX," United said in a statement.

"We continue to automatically book affected customers on other flights and if we can not place them on another flight, we will proactively attempt to offer you other options."

The 737 Max has been stuck around the world since mid-March, after its stall software was involved in two fatal accidents in October and March.

Other major airlines, including American and Southwest, canceled thousands of flights during the summer season, and again removed the Max from their schedules until September 3 and October 1, respectively. These airlines are likely to extend cancellations further.

United announces its second quarter results after the market closes on Tuesday. Delta Air Lines, which does not fly the 737 Max, said Thursday it saw a slight advantage as its rivals struggled with the grounding.

Boeing deliveries are halted until the aviation regulators approve the return to service of the aircraft. The aircraft manufacturer said in June that it would probably take until September or later to introduce a new software patch after the Federal Aviation Administration reportedly identified a new software problem a month ago.
