I needed assistance due to a knee injury and the staff at Air Canada from the checkin right to boarding the plane was incredible! Then on the plane although it was almost full they made it so I DID NOT have anyone seated next to me so I could put my legs up onto the edge of the seat which made things so much easier to travel the hour & a half flight! Very impressed!
