Went back to airport for flight and got denied boarding as was not ticketed on the flight! Agent night prior likely did not properly move me to the flight but was able to issue a BP - odd.

Was delayed 4 hrs to next flight and given $20 in vouchers plus access to MLL when requested. Wrote into Customer relations suggesting $400 was fair as this is what would have been due for a true denied boarding under legislation but acknowledged this was not that. Received a $300 voucher which I think is Ok. Before I heard back from Customer Relations AC also refunded the Aeroplan miles for the flights so that was good.

AC made an error and should compensate in a reasonable way but it’s not a denied boarding per the legislation.
