WestJet is launching a new regional air service operating under a capacity purchase agreement (CPA) with Pacific Coastal Airlines.

Using Pacific Coastal’s aircraft painted in WestJet colours, the service will connect the communities of Lethbridge, Lloydminster, Medicine Hat, Cranbrook and Prince George to WestJet’s network hub at Calgary International Airport (YYC).

All WestJet Link flights will be operated by Pacific Coastal's fleet of 34-seat Saab 340B aircraft.

"A CPA with Pacific Coastal underscores WestJet's commitment to offering more Canadians access to WestJet's low fares and growing network,” said Ed Sims, WestJet’s executive vice-president, commercial.

“WestJet Link will be that connection to these communities and will offer more choice and more competition for air travellers, as well as more opportunities to earn and use WestJet Rewards.”

WestJet has a 52.4 percent capacity share from YYC in 2017, according to OAG, with Air Canada commanding a 34.2 percent share.

Quentin Smith, president of Pacific Coastal Airlines, added: “This new partnership between WestJet and Pacific Coastal will allow smaller communities within Alberta and British Columbia to take advantage of YYC's extensive route network.

“Bringing in new passengers from these communities provides more opportunities to support additional long-haul destinations and contributes greatly to WestJet's growth strategy out of YYC.”

Earlier this month, Calgary-based WestJet filed its results for the three months to the end of September 2017, with record net earnings of CAN$138.4m. The airline achieved its 50th consecutive quarter of profitability and flew an all-time quarterly record of 6.5 million passengers.

Next summer the airline will launch ultra-low-cost carrier Swoop, which will offer a “no-frills, lower-fare travel option”.

Pacific Coastal operates from Vancouver International Airport's South Terminal (YVR). It flies to 15 airports and connects to more than 50 destinations in British Columbia.
