and what's probably happening (contrary to all of those conspiracy believers out there) is that the lack of baseline data to tune the application means that it's probably a bit more "aggressive" at protecting a potential revenue seat than what we've come to expect. That's plausible
Ah, light bulbs turning on
But back to what I think is the root of the problem... it's expectations. I think that Air Canada (right or wrong) has established expectations in us that by holding an upgrade certificate, it means upgrade space is available. By turning it into a "space available" program smacks of deceptive marketing... or bait and switch.
All airlines do this and people have the same expectations with them. Ac needs an outlet for those who don't get I and an E plus type of seat could be the answer. No airline will give up seats specifically for upgrade classes if they can sell the seat at higher prices
"Here's an upgrade coupon - you can confirm an upgrade 72 hrs in advance with an applicable fare basis" = BAIT
Only on a seat available basis
"whoops, our system zeroed out the upgrade class to protect potential revenue because we don't have enough experience in tuning it. Sorry" = SWITCH
Well you can do what some do and buy Discounted C or J to be sure. you are asking for a freebie to be guaranted because your employer won't pay for a higher priced seat.So, you blame the airline?
