From 2017, Abbotsford International Airport began to see a resurgence in air passenger numbers, with the introduction of service to Edmonton and Calgary with WestJet. In 2018, Flair Airlines introduced additional flights to Edmonton, and new flights to Winnipeg and Hamilton. Swoop, WestJet's ULCC subsidiary, began similar operations, with flights to Edmonton, Winnipeg, Hamilton, London (ON), Las Vegas, and seasonal flights to Mazatlan and Puerto Vallarta. Air Canada Rouge offers a seasonal service to Toronto Pearson between June and October. This service was suspended in 2019 due to the 737 Max grounding, and again in 2020 due to the COVID-19 pandemic. It will resume in 2021.
