Looking at their quarterly report.

Their adjusted cost per available seat mile is 15.6 cents.

Looking at what that might mean?

Flight from Edmonton to Toronto - 2000 miles.
Airport taxes per seat at each end 50.00 - total 100.00 for that flight.
For the Edmonton to Toronto run the cost of each seat - 2000*.156+100 = $412.00

So, if that is anywhere near accurate, then if they fill a plane and their average seat price is above $412 then they are making money.
