Sept. 3 (UPI) -- American Airlines said it's extended its grounding of the Boeing 737 Max until December, when it will be on the schedule for the Christmas travel season -- provided it's been cleared to fly by then.
American said in an update it could resume operating the grounded aircraft on Dec. 3. The model has been grounded worldwide since March after two deadly crashes killed more than 300 people. The 737 Max 8 and Max 9 must be cleared by the Federal Aviation Administration before it can return to the skies. Boeing has said it's working on installing a software fix.
