AC E90 -> 320 -> 763
Was booked on a 11am YYZ
(AC408), with the sole purpose of flying an E-Jet for the first time, when they were relatively new.
Unfortunately there was some kind of storm the previous night and apparently the stranded passengers were put on my flight, thus overbooking the flight by 12 people and bumping me off. Was moved to an earlier 10:30am extra section flight on an A320, but they "accidentally" assigned a Jetz A320 in charter configuration (how did they manage to do that?!) to that flight, and only the first 64 passengers were able to board it--I was not one of the first 64.
Then I got put on standby for the 4pm AC416 flight, which left after 5pm after two
gate changes and the ensuing confusion, and was on an old ex-CP 767 that wasn't yet retrofitted to the new cabin.
I was never offered any compensation because they claimed that it was "weather related", which is quite funny as I saw my flight leave without me. Truly a world class airline and deserving of their title of being the best airline in North America. I'm sure they'll win more customers with their practice of inconveniencing even more passengers by putting what's supposed to be stand-by passengers ahead of confirmed ones, and bumping confirmed passengers off with no compensation offered whatsoever.
Other than that,
333->744 (not a huge deal)
The biggest mistake made by most human beings: Listening to only half, understanding just a quarter and telling double.
