Even with Delta’s CrowdStrike meltdown in July, it still had better on-time arrivals performance for the month than American Airlines. The latter was significantly impacted by weather, but the results remain notable.
According to data from airline analytics firm Cirium, Alaska Airlines was the most on-time for July, followed by United. Delta, typically a leader in this category, came in third due to their operational issues following the CrowdStrike outage. JetBlue and Southwest ranked next.
Among U.S. airlines, American outperformed only Frontier and Spirit. "When you’re behind JetBlue something went wrong with your operation," an industry analyst commented. While American attributes its struggles primarily to weather-related disruptions, this has been a recurring explanation. If their hubs are more susceptible to adverse weather during peak travel times in summer, it is a significant factor worth noting.
