Following last Thursday’s party on a Sunwing Airlines flight from Montreal to Cancun, flight attendants are demanding stronger action from government and carriers to ensure passenger and crew safety amid the Omicron wave.

Videos shared of the December 30 flight on social media show  passengers not wearing masks while gathering in close proximity, singing and dancing in the aisle and on seats.

”It’s a slap in the face to see people putting themselves, putting their fellow citizens, putting airline workers at risk by being completely irresponsible,” said Prime Minister Justin Trudeau.

Transport Minister Omar Alghabra says there will be an investigation and that non-compliance with regulations can result in fines of up to $5,000.

The head of the local union representing about 1,000 Sunwing flight attendants, says Sunwing’s the only major Canadian airline that does not offer rapid tests to cabin crews, which Rena Kisfalvi believes should be mandatory.

She adds up to half of her colleagues have had to call in sick over the past month because of potential COVID symptoms.

Meanwhile, Sunwing cancelled the group’s return flight from Cancun scheduled for today, and Air Transat says those passengers will not be allowed in its planes.
