Airbus targets an Entry Into Service (EIS) for the A220-500 around 2032, confirming a simple stretch design philosophy to minimize investment. The variant adds five fuselage frames to the A220-300, retaining existing wings and Pratt & Whitney GTF engines while reducing range for short-to-medium haul efficiency. This 180-seat aircraft bridges the gap between the A220-300 and A320neo, offering lower seat costs for operators needing higher capacity without A320neo size. Formal launch is expected at Farnborough in July 2026, pending board approval and commitments from two to three major customers. Production ramp-up to 14 units monthly remains a prerequisite before finalizing the timeline, with market entry likely in the early 2030s.
