MIAMI — Canadian carrier WestJet will introduce wide-body aircraft in 2015, according to a company release put out on Monday. Currently the airline operates a fleet of Boeing 737s on short to medium haul flying in North America.

Calgary-based WestJet says it is in the “advanced stages of sourcing wide-body aircraft.” Once acquired, the company says the airplanes will be used between Alberta and Hawaii late next year. The jets will replace the current service via two Boeing 757-200s operated by Thomas Cook. New overseas routes are expected in 2016, though the carrier declined to say which routes it is considering.

The release added that the move has already received support of its pilot association and the Board of Directors.

The carrier recently began transatlantic operations from St. John’s in Newfoundland to Dublin on June 15.

The airline also operates a regional arm, Encore, with Q400 aircraft.
