On Air Canada in 2026, SBY stands for "Standby." When you see this on your boarding pass, it means you do not have a confirmed seat assignment at that moment. This typically happens for one of three reasons: the flight is oversold and the airline is waiting for "no-shows," you are a passenger on a Basic Economy fare where seats are only assigned at the gate, or there has been an equipment change (down-gauging) to a smaller aircraft. In 2026, Air Canada’s system automatically ranks standby passengers based on their frequent flyer status (Aeroplan Elite) and fare class. If you are at the top of the SBY list, you will likely receive a seat assignment 15–30 minutes before departure. If you are eventually "bumped" from the flight due to overbooking, 2026 Canadian air passenger protection regulations entitle you to compensation ranging from $900 to $2,400, depending on the length of your delay. It is best to check in with the gate agent as soon as you arrive to confirm your position on the SBY list.
