As the smallest jetliner in Airbus' commercial aircraft product line, the A220-100, was built from the ground up to serve the 100-135 seat market with unbeatable efficiency and comfort.

The smallest aircraft currently in the Airbus lineup is the Airbus A220-100. While it was originally developed by Bombardier as the CSeries, it is now a core part of the Airbus family. The A220-100 typically carries between 100 and 120 passengers and is prized for its "small jet" efficiency combined with a "big jet" cabin feel, featuring 2-3 seating and large windows. If you look strictly at the traditional A320 family, the A318 (often nicknamed the "Baby Bus") is the smallest, measuring only 31.44 meters (103 feet) in length and carrying roughly 100 passengers. However, the A318 is no longer in active production and is becoming increasingly rare in commercial fleets. In 2026, the A220-100 serves as the primary narrow-body solution for thin, long-range routes that don't justify a larger aircraft. Its modern engines and aerodynamic design make it significantly quieter and more fuel-efficient than the older, smaller regional jets it is designed to replace.
