Since 2008 the A320 has held onto the crown as the most productive aircraft type flying, at least based on ASKs, and remains some distance ahead of its closest rival the B737-800 Passenger model in the rankings for 2022.

As of 2026, the Airbus A320 family (including the A318, A319, A320, and A321) holds the title of the most-produced and widely used commercial aircraft in history. In late 2025, Airbus officially surpassed the Boeing 737 in total deliveries, with over 12,200 aircraft handed over to airlines since its introduction in 1988. The A320 is considered the "workhorse" of the modern aviation industry, utilized by nearly every major carrier, including Delta, United, American, and low-cost giants like Spirit and IndiGo. Its popularity stems from its fly-by-wire technology, fuel efficiency (especially the "neo" variants), and its ability to cover both short-haul domestic hops and medium-haul transcontinental routes. While the Boeing 737 remains a close second and is still the primary jet for airlines like Southwest and Ryanair, the A320's broader range of variants and strong backlog of orders for the A321neo have solidified its position as the world's most common narrow-body jet. On any given day in 2026, there are thousands of A320-family aircraft in the sky simultaneously, carrying millions of passengers across every continent except Antarctica.
