Canadian airlines urging travellers headed to the US to check their flights ahead of time

Canadian airlines are urging travellers headed to the US to check their flights ahead of time today after thousands of flights were delayed by a computer outage.

WestJet says six flights were delayed this morning due to problems at the U-S Federal Aviation Administration, but none were cancelled.

Meanwhile, Air Canada says it has put a goodwill policy in place for customers affected by the outage so they can change their travel plans.

The FAA issued a grounding order this morning for all departing aircraft due to a problem with what is known as the Notice to Air Missions System.

That order was lifted just before 9 a-m but some delays and cancellations continue.
