WestJet has sealed its plan to buy 65 737 MAX aircraft from Boeing following its letter of intent announced in August. The $6.3bn order includes 40 737 MAX 8s and 25 737 MAX 7s. “We are pleased to announce the finalisation of the MAX purchase agreement and look forward to being among the first North American airlines to fly the 737 MAX in 2017,” said WestJet’s president and CEO, Gregg Saretsky. He added that the aircraft are “supportive of our low-cost business model and combined with our lease renewal options, maintains our fleet plan flexibility going forward”. WestJet’s deal brings the total number of 737 MAX orders to 1,567.
