WestJet will wind down its Swoop subsidiary by late October as it integrates the budget carrier’s operations into its main banner, the airline said Friday. The move comes after pilots with the two airlines ratified a new collective agreement that brings them onto a level pay scale.

It comes five years after Swoop first surfaced as a response to discount rival Flair Airlines’ launch in 2017.

WestJet CEO Alexis von Hoensbroech said he mulled keeping Swoop separate, but that higher wages for its flight crews made the option less realistic.

“We were prepared for both possible outcomes, and then decided that, provided the overall didn’t make sense, we’re actually ready to integrate Swoop into the mainline business,” von Hoensbroech said.

Each trip by planes in the carrier’s 180-plus fleet will offer a portion of ultra-low-cost fares by Oct. 29, the day after Swoop ceases to fly, he said, adding that no bookings would be affected.

“We are actually broadening our ultra-low-cost reach to a much, much broader network than we could have ever covered with Swoop. So, therefore we actually see this as an advantage and as an increased footprint for the ultra-low-cost offering in Canada.”

Pilots of WestJet and Swoop secured a 24% pay bump over four years under a deal agreed on tentatively last month that narrowly averted a strike.

Bargaining came down to the wire, with WestJet cancelling more than 230 flights in preparation for job action before a deal was reached hours ahead of the strike deadline on May 19.

Competition for budget airfares has grown in recent years, particularly in Western Canada, as upstarts Flair Airlines and Lynx Air challenged Swoop for market share on key routes.

“The market has become pretty competitive,” von Hoensbroech said, but insisted Swoop’s integration strengthens its grip on discount offerings, rather than marking a retreat.

The company said no layoffs are expected from the integration, with all Swoop employees slated to move to the mainline.
