It is important to check your name twice on the ticket before flying with Air Canada. In some circumstances, a passenger’s name may be mentioned incorrectly on the flight ticket, hence, for this reason, the Air Canada name correction policy permits you to rectify it. The correction can include your surname, initial name, as well as a middle name. However, you can correct up to a few letters in your entire name.
