CHICAGO (AP) — United Airlines said Friday that it is dropping its 14 Boeing 737 MAX jets from the schedule until Nov. 3 — a month longer than previously planned.

The airline says that without the Max jets, it will cancel 40 to 45 flights a day this month, with that rate rising to about 95 canceled flights per-day in October.

That would mean it has cancelled more than 8,000 flights from March through October because of the MAX grounding.

The Max was grounded around the world in mid-March after the second of two deadly crashes that killed 346 people.

Boeing is working to fix flight control software that appeared to play a role in the crashes in Indonesia and Ethiopia, according to preliminary accident reports.

Both companies have their headquarters in Chicago.
