Alberta, Canada-based airline WestJet has finished integrating Sunwing Airlines with its operations.
According to a news release published by WestJet Group on Wednesday, the milestone comes after two years of coordination efforts with its Toronto-based subsidiary.
WestJet began absorbing Sunwing Airlines and Swoop in summer 2023, shortly after purchasing both Canadian ultra-low-cost carriers that same year. WestJet stated in its release that the move is aimed at “delivering greater value and connectivity for Canadian travelers.”
“Completing two airline consolidations in just two years—the first with Swoop in 2024 and now Sunwing—was complex and required coordination across every aspect of our business, from operational, labour, and regulatory areas to experiential and cultural elements,” said Alexis von Hoensbroech, CEO of WestJet Group, in the release. “Achieving this milestone is proof of the incredible way our unified team works together and is a clear win for WestJet and our guests; it’s also a story of transformation in Canadian aviation. A huge thanks to everyone who contributed!”
Both integrations bring all 16 Swoop and 18 Sunwing aircraft under a single Air Operator Certificate (AOC). Nine former Lynx Air aircraft acquired after that airline went out of business in February 2024 were also included on the AOC.

WestJet’s newly unified narrowbody operation expects a boost in efficiency after the airline transforms these aircraft with cabin edits this year. The carrier stated that premium, economy, extended comfort and ultrabasic seating will be available on all 150 of its Boeing 737 aircraft once these reconfigurations are completed.
“The final Sunwing-operated flight this week is a time to reflect,” von Hoensbroech said. “I know every Sunwing employee, past and present, feels their contributions have mattered to advancing the experience of air travel. To all WestJetters and former Sunwing team members: thank you. This milestone is your achievement, and a proud moment for us all.”
