Calgary’s WestJet is moving forward with plans to acquire four widebody aircraft for long-haul operations starting in late 2015. The type is yet to be determined.

The airline said it has received support from the WestJet Pilot Association and its board of directors, and is currently in the advanced stages of sourcing the aircraft.

“This is the natural, next-step evolution for WestJet,” WestJet president and CEO Gregg Saretsky said.

Initially, WestJet expects to deploy the aircraft on routes between Alberta and Hawaii during the winter season beginning in late 2015. The airline currently uses two Boeing 757-200s, operated by Thomas Cook, on the service; this contract ends in the spring of 2015.

WestJet said further announcements regarding its widebody schedule for the 2016 summer season will be released at a later date as it looks to expand into overseas markets.
