Travellers flying out of Vancouver International should expect delays due to a blackout at the airport Friday morning.
Backup generators were able to keep things operational at the international terminal, the Vancouver Sun reports. But those flying domestic weren't as lucky, as that section was left in the dark for roughly 30 minutes.
UPDATE: All backlogs have been cleared and flight schedules at the airport have returned to normal.
Power was has since been restored but the outage resulted in delays as long as 90 minutes, according to CBC News.
A power outage means that YVR lines are outrageously long. Can't even see the front of it from here. I may walk home. pic.twitter.com/42JtSPDmmt— David (P) Leonard (@davidpleonard) May 23, 2014
It's still uncertain as what caused the blackout, but BC Hydro told Global News the issue is believed to be internal since it didn't register on their systems.
Airport staff urge all travellers to check flight times at the airport website or with their carriers.
