Air Canada has issued a travel advisory for flights coming into and out of Vanvouver on Sunday, saying an expected snow storm in southwestern B.C. is likely to cause delays and even cancellations.

As a result, Air Canada and Air Canada Jazz have issued the following advice: 

Customers with flights to and from the affected areas who wish to make alternative travel arrangements to travel earlier or later can do so without penalty, space permitting, through Air Canada Reservations at 1-888-247-2262; TTY hearing impaired: 1-800-361-8071. Certain conditions may apply

Meanwhile, the South Coast British Columbia Transportation Authority (TransLink) said it is monitoring the situation. So long as the roads are clear, it says the buses can get through.

Metro Vancouver's SkyTrain service will be running longer-than-usual trains, with SkyTrain attendants at all station platforms to deal with any weather-related issues.

Bus and SkyTrain passengers have been warned to dress appropriately and to expect possible longer-than-usual waits at bus stops and that.

If buses have to be detoured due to snow, passengers may have to walk a distance, a Translink spokesman said.
