VANCOUVER -- Travellers heading out of Vancouver Wednesday are being warned that the weather could have an impact on flights.

Wednesday morning saw dozens of cancellations and delayed flights out of Vancouver International Airport as the region was hit by more cold weather and snow.

All planes are having to go through a de-icing process, adding about 15 minutes extra to each flight. As a result, a number of short-haul flights were cancelled, including some flights to and from Victoria, Nanaimo, Prince George, Seattle and Comox.

YVR’s vice president of engineering says that’s because the same plane is making the same trip a number of times through the day, and needs to be de-iced before take-off.

“For example, we have about 25 or 30 flights to Victoria in a day, and the airlines would have cancelled some of those flights and proactively booked their passengers on other flights to Victoria.” Don Ehrenholz said. “You have to remember that the whole region, including Victoria, Nanaimo, all the local towns and cities you might fly to also are experiencing a lot of snow. Out of our overall 650 to 700 flights, probably 30 to 35 flights have been cancelled today.”

Some longer-haul flights have seen half-hour delays, but Ehrenholz says nothing too significant. He also adds check-in and boarding is running as normal.

The major headache for travellers is getting to the airport. With the snow causing issues on transit, many people chose to drive, resulting in heavy delays getting to the terminal.

Seaplane traffic was also affected by weather Wednesday. Most Harbour Air flights between Vancouver and Victoria were cancelled. Shortly before 3 p.m., the airline tweeted that it would be closing its reservations department at 5 p.m. "due to the poor weather conditions and increased snowfall."

As the snow sets in again Wednesday afternoon, the delays and cancellations are set to continue. Travellers are being told to check with their airline for updated information.

A wind warning is also in effect for Metro Vancouver with gusts of up to 90km/h expected. Ehrenholz says it could be bumpy but there are no major concerns.
