A data company has figured out which airlines fly on time most often

Aeromexico is the most on-time airline in the world, according to a data company that compiled figures for 2024. Cirium said in its annual ranking released on Thursday that nearly 87% of the Mexican airline's flights were on time in 2024. That puts Aeromexico slightly ahead of Saudi Arabian airline Saudia and Atlanta-based Delta Air Lines. Delta was the best-scoring U.S. airline despite a July computer outage that caused thousands of flight cancellations. Canadian airlines WestJet and Air Canada, along with Denver-based budget airline Frontier, were at the bottom of Cirium's rankings among airlines in North America.
