Virgin Atlantic will operate five weekly services between London Heathrow and Vancouver next summer.
The seasonal service between the two cities will relaunch on May 22 and run until October 11 - during this period flights will be deployed on Tuesdays, Thursdays and Saturdays.
However, between May and August a fourth flight will operate on Sundays, while from July to September another service will fly on Wednesdays.
Therefore, during the overlap period in July and August, the LHR to Vancouver route will become a five-weekly service.
Edmond Rose, director of airline planning at Virgin Atlantic, said: "Our Vancouver service was launched in 2012 and has been proving popular since its inaugural with demand remaining high throughout the summer months. Since its launch we've flown 17,214 passengers to Vancouver.
"We currently run a seasonal service four times a week from London Heathrow to Vancouver and we are delighted at its popularity.
"To meet this demand we have taken the decision to introduce a fifth weekly service next summer, resulting in a strong increase in the number of seats available for holiday makers looking for a getaway to British Columbia."
Last month, Virgin Atlantic and Delta Air Lines revealed how they will align their services at eathrow ahead of their transatlantic joint venture (see news, November 11).
