Air Canada operates a fleet of long-haul aircraft, with the Boeing 777-300ER boasting the largest passenger capacity. The airline's focus on this aircraft underscores its importance for transoceanic routes. The Boeing 777-300ER, used on transatlantic and transpacific routes such as Montreal to Athens, Toronto to Rome, and Vancouver to Tokyo, can accommodate up to 450 passengers, making it the largest-capacity aircraft used by any North American airline. "Air Canada’s 450-seat Boeing 777-300ER is the highest-capacity equipment used by any North American airline," says Simple Flying.
The airline's fleet in 2025 includes 207 mainline aircraft, with a combination of narrowbody and widebody models from Airbus and Boeing. Specific configurations of the 777-300ER include high-density and standard models, allowing flexibility to meet various demand levels.
These aircraft feature three cabin classes: Signature Class, premium economy, and economy. Signature Class offers lie-flat beds, while the economy is arranged in a 3-4-3 layout, a configuration that ensures efficient use of space for high-demand routes. Looking ahead, Air Canada may further expand its Boeing 787 fleet and update its A320 series, but the Boeing 777-300ER is expected to remain integral to their operations during peak travel periods.
