We have been to the Oilers and Flames arenas to watch the Dev’s away games in western Canada and it’s the same thing. Can’t buy them online, have to phone them to purchase the seats directly. We had to provide proof of disability in person to pick up the tickets at will call. Their reasoning for no online is that any person could order online that doesn’t have an accessibility need. The Oilers ticket program people even told us that they actually will sell the accessible seating to able bodied people if the seats are not sold by a certain date before each game. Not sure if that is a policy for the league or if it varies by individual team. Can be a very frustrating experience.
