The Air Canada flight attendant labor strike has impacted flights at Phoenix Sky Harbor International Airport.

Flights from Phoenix to Montreal, scheduled to leave at 7:16 p.m. on Aug. 16 and at 7:40 a.m. on Aug. 17, were both canceled, according to the Sky Harbor website.

Air Canada carries an estimated 130,000 passengers daily, the airline said, and Phoenix Sky Harbor Airport has three nonstop Air Canada routes: Montreal, Toronto and Vancouver, British Columbia.

Air Canada announced on Aug. 16 that the company had suspended all operations of Air Canada and Air Canada Rouge due to a strike by its 10,000 flight attendants, according to a written statement released by the airline.

Flights by Air Canada Express were not affected as they were operated by third-party airlines, according to Air Canada.

The strike took effect at about 1 a.m. ET. on Aug. 16, after the statutory 72-hour strike notice.

The Canadian Union of Public Employees, which is representing the striking flight attendants, served Air Canada a 72-hour strike notice on Aug. 13. The strike took effect at about 1 a.m. on Aug. 16, according to Air Canada.

“Air Canada is strongly advising affected customers not to go to the airport unless they have a confirmed ticket on an airline other than Air Canada or Air Canada Rogue,” Air Canada said in a written statement.

Officials at Air Canada said customers with upcoming travel plans would be notified of additional canceled flights and the options provided to them, according to the Air Canada website.

A goodwill policy was instated, allowing customers whose flights were not canceled to rebook their travel plans or obtain a credit for future travel, according to the Air Canada website.
