Swoop, the standalone ultra-LCC subsidiary of Canada’s WestJet scheduled to launch in June, could eventually have a fleet of as many as 40 aircraft, WestJet CEO Gregg Saretsky said. Swoop—for which flight tickets started being sold last week—will launch with three Boeing 737-800s densely configured with 189 seats. It will initially operate on domestic Canadian routes, but Saretsky said Swoop aims to fly to some points outside of Canada before the end of this year
