Air Canada offers online, mobile, and airport check-in options for passengers. The most convenient way is online check-in, which becomes available 24 hours before the scheduled departure of your flight. You can check in through Air Canada's website or mobile app using your booking reference number and last name. During online check-in, you can choose your seat, confirm flight details, and get your boarding pass digitally. If you’re only carrying hand luggage, you can head straight to security.
If you have checked baggage, you should still arrive early at the airport to drop off your bags at the baggage counter. For domestic flights, arrive at least 2 hours before departure. For international flights, it's best to be there at least 3 hours before. Airport check-in counters open about 3 hours before the flight and close 45 to 60 minutes before takeoff, depending on the route.
Air Canada also provides self-service kiosks at many airports where you can check in, print boarding passes, and baggage tags. Using online or kiosk check-in saves time and helps avoid long lines. It’s always a good idea to arrive early, especially during busy travel seasons.
