Recording since 2026-10-14.
The FAA keeps no public history, so this is only what we have polled (every 15 minutes).
Sources. Delay rates: US DOT Bureau of Transportation Statistics, Reporting Carrier On-Time
Performance (public domain). It covers domestic flights on airlines with at least 0.5% of US domestic
passenger revenue, about 600,000 flights a month; smaller carriers and international flights are not in it.
Live status: FAA Air Traffic Control System Command Center, NAS Status (public domain). Airport locations:

Definitions. Late means 15+ minutes after schedule, out of flights that operated. Causes are reported by airlines for arrivals 15+ minutes late. "Late aircraft" is the knock-on from an earlier delay to the same plane, so it says nothing about where the trouble started. "Air traffic" (the NAS category) covers airport capacity, traffic volume and non-extreme weather. "Usual" is the median of the same month in up to five earlier years, with 2020 left out; it appears once two earlier years exist.
