Canada

I did some quick, very rough math.

Transport Canada requires 1 FA:40 passengers (and the least efficient planes have a ratio of about 1:30)

From what I could find (please correct me if I'm wrong) the average flight attendant makes ~$30/hr, but only while the doors are closed.

I don't imagine they're asking for a 33% raise, but it makes the math easier.

$10/hr ÷ 40 people = 25¢ per person per flight hour

I have no idea how much unpaid work they do during a turnaround related to each flight, but I imagine it's not less than an hour and not more than 2 hours. So at $40/hr total wage that would add $1-2 per person per flight.

So on the worst case scenario/longest flight (YVR-SIN, 16hrs, 298 passengers, 8+2 Flight attendants, 30:1 ratio) that would be ($0.25*16+$2)+33%= ~$8 extra per person.

In a highly competitive marketplace (which air travel is), companies can't raise prices to cover increased input costs. Their prices are determined by what consumers are willing to pay relative to what their competitors charge, not what their product costs.

It's one of the Big Lies people have been taught to believe - "if you make things more expensive for them, they'll just raise prices!"

They don’t need to raise ticket prices whatsoever. They’re taking in massive profits, as the airlines have been openly price-fixing for over 15 years. They would just have to cut into the profits to executives and investors.
