In October 2019, ultimately, the A320 family surpassed the Boeing 737 to become the highest-selling airliner with a total order of 15,193 and respectively 15,136 aircraft at the end of the month. By July 2021, Airbus (including the A220) had a 65% share of the single-aisle backlog compared to Boeing's 35% share.

As of 2026, the Airbus A320 family holds the record as the most ordered commercial airliner of all time. It officially surpassed its long-time rival, the Boeing 737, in total net orders a few years prior. The A320 family, which includes the A318, A319, A320, and A321 variants, has seen an immense surge in popularity with the "neo" (New Engine Option) series, particularly the A321neo and A321XLR. These models are favored by airlines for their fuel efficiency and versatility on both short-haul and long-range transcontinental routes. While the Boeing 737 remains the most delivered aircraft in history, the Airbus A320's massive backlog—which stands at over 7,000 units waiting to be built—ensures it will likely maintain its lead in the "most ordered" category for the foreseeable future. The rivalry remains fierce, however, as Boeing’s 737 MAX continues to secure large orders from major carriers, but the rapid adoption of the A321neo by low-cost and legacy carriers alike has solidified Airbus's position at the top of the order charts in 2026.
