MONTREAL — Air Canada will renew its mainline narrowbody fleet with commitments, options and rights to purchase up to 109 Boeing 737 MAX aircraft.

The new aircraft will replace Air Canada’s existing mainline fleet of Airbus narrowbody aircraft, creating one of the world’s youngest, most fuel efficient and simplified airline fleets.

The agreement with Boeing, which is subject to completion of final documentation and other conditions, includes firm orders for 33 737 MAX 8 and 28 737 MAX 9 aircraft with substitution rights between them as well as for the 737 MAX 7 aircraft. It also provides for options for 18 aircraft and rights to purchase an additional 30.

Deliveries are scheduled to begin in 2017 with two aircraft, 16 aircraft in 2018, 18 aircraft in 2019, 16 aircraft in 2020 and nine aircraft in 2021, subject to deferral and acceleration rights.

Air Canada continues to evaluate the potential replacement of its Embraer E190 fleet with more cost efficient, larger narrowbody aircraft that are better suited to its current and future network strategy. Consistent with this strategy, the agreement with Boeing provides for Boeing to purchase up to 20 of the 45 Embraer E190 aircraft currently in Air Canada’s fleet. The E190 aircraft exiting the fleet will be initially replaced with larger narrowbody leased aircraft until the airline takes delivery of the Boeing 737 MAX aircraft.
