American Airlines Group says first Boeing 737 MAX flights in December

American Airlines Group said on Wednesday it would make good on its plan to return Boeing Co’s 737 MAX jets to passenger flights by the end of 2020 after the planemaker won U.S. Federal Aviation Administration (FAA) approval to fly them again.

The No.1 U.S. airline said it will begin with non-commercial flights in early December before resuming passenger flights later in the month.
