The American carrier is reducing its international flights due to Boeing's ongoing incapability to deliver its 787-8 Dreamliners on order.
The airline will postpone the launch of its Fort Worth - Tel Aviv route and lower its Miami to Sao Paolo, Brazil route to a single daily service.
American is also temporarily suspending Seattle - London Heathrow, Fort Worth - Pudahuel, Chile, and Los Angeles - Sydney routes.
American was expecting to take delivery of all 13 787 Dreamliners on order this year, but instead, it will receive only 10 of them this year with the remaining three to be delivered next year.
Boeing halted the deliveries of 787s in late May 2021 after the Federal Aviation Administration (FAA) raised concerns over the planemaker's quality control approach.
This suspension is expected to go on for months as the American regulator said last week that Boeing cannot self-certify the planes.
