Routes with the most delays

Among routes with at least 1,200 scheduled flights by reporting carriers in the 12 months to July 2026 (about 100 a month), the 100 with the lowest share arriving on time, followed by the 100 with the highest. National share: 76.0%.

BTS: A flight is counted as on time if it arrived less than 15 minutes after its scheduled time. Only carriers with at least 0.5 percent of domestic scheduled passenger revenue report. Cancelled and diverted flights count as not on time. A route's figure reflects both airports, the season mix and the hours flown as much as the carriers on it.
