The Vancouver Sun reports in its Wednesday edition that WestJet Airlines says it is making progress on its plan to start Canada's first ultralow-cost carrier (ULCC), but that it is pushing the targeted launch back from late 2017 to summer 2018. Postmedia's Alicja Siekierska writes that the airline will use what WestJet calls a "fleet of 10 high-density Boeing 737-800s" for the venture. WestJet chief executive officer Gregg Saretsky said on a conference calll that the delay was in part because the company wanted to avoid having to reconfigure the 10 Boeing 737-800 jets during the peak travelling season. "Those aircrafts will now be reconfigured next spring. They would have been done over the Christmas holiday period to be available for flying revenue service in January, and we'd rather not take that hit to capacity during a very strong time of year," he told analysts Tuesday. WestJet said it is hiring staff for the ULCC and plans on moving them to a separate location during the first quarter of the following fiscal year. The airline also plans to use an older reservation system that Mr. Saretsky said is "perfectly suited for point-to-point low-cost travel and has significantly lower transaction costs."
