Aeroméxico (AM, México City International) took delivery of its first B737-9 ahead of the type's planned entry into service scheduled for June 7, 2021.

XA-IMH (msn 43711), an aircraft built during the B737 MAX family grounding in 2019 and stored since then at Renton and Moses Lake airports, was ferried from Seattle Boeing Field to México City International on May 28, 2021, Flightradar24 ADS-B data shows. The Mexican carrier owns the aircraft.

Aeroméxico's first B737-9 joined six B737-8s already in the carrier's fleet. Officially, the carrier has a further eleven B737-8s and forty-three -9s on firm order from Boeing, although a recent agreement approved by a US bankruptcy court will see the airline drop two -8s and thirty-two -9s. As such, it unfilled orders now number nine -8s and eleven -9s.

As reported previously, Aeroméxico plans to induct the -9 into revenue service on trunk domestic routes on June 7, 2021. The first flight is scheduled from Mexico City to Tijuana.
