Pacific Coastal appears set to expand its operations on behalf of Westjet once again. The Canadian Transportation Agency has given the regional airline permission to operate Westjet Link flights to the United States.

The two airlines have been partners for more than a year, with Pacific Coastal operating smaller Saab 340s that can seat up to 34 passengers on behalf of Westjet.

In a decision released September 3, the CTA – Canada’s airline regulator – said Pacific Coastal met the requirements to operate a transborder service using small planes. No details have been released about what service Westjet has in mind or when it might get off the ground.

Westjet Link is a capacity purchase agreement between Westjet and Pacific Coastal, service smaller cities, mostly from Westjet’s Calgary hub, though Link will open a new service between Cranbrook and Vancouver this fall.

This would be Pacific Coastal’s first foray into scheduled service to the U.S. The airline is the third-largest user of Vancouver International Airport, specializing in flights within British Columbia, and using Vancouver’s South Terminal as its base.
