Airbus A220-100

The Airbus A220-100 typically seats 108 passengers in a two-class configuration. Maximum single-class capacity is 135 passengers. Despite being smaller than the A220-300, it features the same wide cabin at 3.28 m with a 2-3 seating arrangement, meaning only one side of the aisle has a middle seat.

The Airbus A220-100 has a maximum range of approximately 5,460 km (2,950 nautical miles). This range covers routes like New York to Denver, London to Istanbul, or Dubai to Mumbai. The aircraft uses Pratt & Whitney PW1521G geared turbofan engines, which are 20% more fuel-efficient than previous-generation engines in this size category.

The A220-100 is 3.7 m shorter than the A220-300, carrying about 22 fewer passengers (108 vs 130 in two-class). Both share identical wings, engines, cockpit, and systems, offering complete fleet commonality. The A220-300 has better per-seat economics and has received far more orders, accounting for roughly 80% of total A220 family sales. The A220-100 is better suited for thinner routes where the larger variant would not fill enough seats.

The A220-100 shares the A220 family's sleek design with raked wingtips, large cockpit windows, and distinctive Pratt & Whitney geared turbofan nacelles. At 35.0 m, it is noticeably shorter than the A220-300's 38.7 m. The belly-mounted landing gear fairing is a unique A220 feature. The shorter fuselage gives it slightly more compact proportions than the -300 variant.

The A220-100 was originally developed by Bombardier as the CS100, the first variant of the C Series program. Swiss International Air Lines was the launch operator, receiving its first CS100 in June 2016. After Airbus acquired the program in 2018 and rebranded it, additional customers included Air Tanzania and Delta Air Lines. The A220-100 has sold fewer units than the -300, but it fills an important niche for airlines needing a modern, efficient aircraft in the 100-120 seat range.
