Canadian carrier WestJet is to further expand its domestic offering between Vancouver and Toronto as Canadians prepare for the busy summer travel season. The airline will add more than 20 additional flights to its schedule between May 3, 2015 and October 24, 2015, strengthening its position in a dominant Air Canada city pair market.

The revised schedule will see the airline boost its inventory by more than ten per cent to offer up to ten daily flights in the spring, eleven during the peak travel months of July and August, and nine in the autumn.

"This is the time of year when many Canadians sit down to make their summer travel plans," said Chris Avery, vice president, network planning, alliances and corporate development, WestJet. "Our extensive domestic, transborder and international network of more than 90 cities in 20 countries opens up a world of possibilities.”

WestJet also offers up to 12 daily non-stop flights between Calgary and Toronto, nine from Edmonton to Toronto and six from Winnipeg to Toronto. From Toronto, guests connecting eastward have ten cities in Quebec and Atlantic Canada to choose from, as well as eight destinations in the United States and 21 throughout Mexico, the Caribbean and Central America.

"The confidence and trust Canadians have in WestJet allows us to continue to grow and offer more destinations," said Avery. "As we approach our 19th birthday at the end of this month, we are enormously grateful for their support and loyalty."

WestJet's growing network now includes Europe, with flights to the UK commencing from May 29, 2015, with a seasonal daily offering between Toronto and Glasgow, Scotland, via Halifax. This follows the airline's successful launch of its first transatlantic service between Toronto and Dublin, Ireland, via St. John's, last summer which will resume from May 1, 2015.
