UPDATE: 1:30 p.m.

Crews are scrambling to fix a broken de-icing machine, which has caused delays for Air Canada flights at Kelowna International Airport Sunday.

Frustrated passengers have been stuck inside a departing aircraft since 11:05 a.m.

“It has nothing to do with baggage, the company that does the de-icing for Air Canada had a mechanical failure,” said Sean Parker spokesperson for YLW.

“They are working on it right now,” he said.

An alternative plan is in process to de-ice the aircraft and is expected to take 30 minutes. 

“The truck is going to be up shortly, but we have a backup plan we are rolling out right now,” said Parker.

The mechanical failure has caused delays for other Air Canada flights.

“They are scrambling to get it sorted out right now,” he said. “It has caused an issue for Air Canada absolutely there is a bit of a snowball effect.”

Passengers have been sitting inside an aircraft for two hours after their departing flight from Kelowna International Airport has been delayed.

Air Canada flight 1185 to Vancouver was expected to leave Kelowna at 11:05 a.m. but has not left the tarmac.

“Pilot stated Kelowna operations staff shortages will result in late baggage loading delayed 40 minutes and counting,” said Jim Marshall who is onboard the flight.

Marshal said it seems the airport is at a standstill.

"Things have gone from bad to worse, people are missing connections," he said.

Castanet reached out to YLW for comment but have not received a response at the time of publication.

Departing Air Canada flights 8415 and 8417, WestJet flight 3325 and Flair Airlines flight 8310 are all delayed.
