Swoop is a Canadian ultra low-cost carrier (ULCC) owned by WestJet. It was officially announced on September 27, 2017, and began flights on June 20, 2018. The airline is based in Calgary and was named after WestJet's desire to "swoop" (or jump) into the Canadian market with a new business model. Shortly after launch, WestJet announced that Swoop would not be based in Calgary, but in another nearby market like Edmonton, Abbotsford, Hamilton or Winnipeg. On February 1, 2018, Swoop officially began selling tickets to the public, announcing John C. Munro Hamilton International Airport as their main base and Edmonton International Airport as their western base. In October 2020, Swoop switched its eastern base to Toronto Pearson International Airport.
