WestJet has signed with Boeing for up to 20 787-9 Dreamliner aircraft with the first 10 to be delivered between the first quarter of 2019 and December 2021.

The second 10, which are options are to be delivered between 2020 and 2024.

The airline also announced it has selected General Electric's GEnx-1B engine for the 787.

"This order represents an exciting new chapter in WestJet's history," said Gregg Saretsky, WestJet President and CEO.

"We have carefully executed on our strategic plan, first launching WestJet Encore to connect smaller communities across Canada to our growing network followed by our successful venture into wide-body flying to Hawaii and London Gatwick.

Now, with the most sophisticated commercial airliner available, we turn our attention to further growing our international presence and introducing, even more, travellers to our award-winning guest experience."

"With a range of more than 14,000 kilometres, the Dreamliner will give WestJet the ability to serve new destinations in Asia and South America and to expand its service offerings into the European market.'' 

Ray Conner, Vice Chairman of The Boeing Company said "we welcome WestJet to the Dreamliner family and look forward to the new destinations they will serve."

Our ability to compete globally and deliver our plan comes from the hard work and dedication of our more than 12,000 WestJetters and I am excited for what this news represents for them," continued Gregg Saretsky.

"They are truly representative of our Canadian values of warm hospitality and openness and on behalf of them, we now turn our attention to welcoming the Dreamliner to the WestJet family."

As part of this purchase agreement, WestJet is converting 15 firm orders for the Boeing 737 MAX that were to be delivered between 2019 and 2021 to options available between 2022 and 2024.
