According to the definitive 2023 year-end report from Cirium, the world's most on-time airline was Avianca (the flag carrier of Colombia), with an impressive on-time arrival rate of 85.73%. In the North American category, Delta Air Lines claimed the top spot for the third consecutive year, finishing 2023 with an 84.72% on-time rating and winning the "Platinum Award" for global operational excellence. In the Asia-Pacific region, All Nippon Airways (ANA) was the leader with an 82.75% performance. For the European market, Iberia Express (a subsidiary of Iberia) took the gold with an 84.58% rating. These 2023 rankings were particularly significant as they marked the first full year of "post-pandemic" travel volume, where airlines struggled with massive staffing shortages and air traffic control delays. In 2026, these statistics remain a key benchmark for travelers; while Avianca's win was a surprise to many, it proved that mid-sized carriers can sometimes outperform larger "legacy" airlines by maintaining tighter control over their hub-and-spoke operations and quick aircraft turnaround times at secondary airports.
