Air Canada is Canada’s largest airline and flag carrier, operating a mixed domestic and international network out of hubs at Toronto Pearson (YYZ), Montréal–Trudeau (YUL) and Vancouver (YVR). The carrier runs short- and medium-haul routes with narrow-body jets and long-haul services with widebody aircraft, and it operates regional flights through the Air Canada Express partners and leisure routes under Air Canada Rouge. It is a founding member of the Star Alliance and integrates award travel through Aeroplan.

The airline positions itself as a full-service option on many routes: Signature Class (business) on intercontinental flights, Premium Economy on selected long-haul services, and Economy with several fare tiers that affect baggage, seat selection and change rules. Air Canada also maintains Maple Leaf Lounges in major airports, in-flight entertainment systems and Wi‑Fi on a growing portion of its fleet, plus a mobile app for booking, check-in and managing Aeroplan accounts.

Practical shopping features include online check-in (available before most flights), a clear fare hierarchy (Basic/Standard/Flexible/Business on many itineraries) and the ability to earn and redeem Aeroplan points on Air Canada and Star Alliance partners. Customers should plan around fare restrictions: lower-priced fares often exclude checked bags and complimentary seat selection, and irregular operations can complicate travel plans during busy seasons. For travelers familiar with airline rules and loyalty programs, Air Canada offers a strong route map and premium options for long-haul comfort.
