Seattle - Alaska Airlines has converted its order of 15 Boeing 737 MAX 8 to MAX 9, bringing the total number ordered of this model to 32.

Last year, the Seattle-Tacoma- based US carrier announced a firm order for 20 MAX 8 and 17 MAX 9, with deliveries spread between 2019 and 2023. Later, Alaska Airlines revised its MAX 8 order as 15 aircraft, and now zero by converting all of them to MAX 9.

The 32, 737 MAX will all be in MAX 9 version. The cabin configuration of the MAX 9s has not unveiled yet, but the 737-900 and 900ERs of the airline (80 in service, 11 waiting for delivery) can accommodate 16 passengers in Business class, 24 in Premium and 138 in Economy. Alaska Airlines chose the Recaro seats to equip its Boeing 737 MAXs.

Alaska Airlines also confirmed a reduction in deliveries expected in 2019, to 12 aircraft against 24 originally planned: an Airbus A321neo (7 in service, 10 expected), four Embraer 175 (38 in service at Horizon Air and SkyWest, 30 expected) and seven 737-900ER.

Recall that the operator also signed for thirty A320neo intended initially for Virgin America, whose brand has just disappeared from the American skies sixteen months after the merger of two companies.
