Delay window: January 2023 to December 2025. Cancellation window: 2024 to 2025. Last updated: 2026-10-18. Delayed means a flight arrived 15 or more minutes after its scheduled arrival, the BTS and DOT on-time standard. Cancelled and diverted flights are excluded from delay rates. Historical BTS figures are separate from DelayGuard's per-flight model probability and from live FAA, weather and ground-delay status.

Sample size: 112,509 flights, window: January 2023 to December 2025. Delay rate 19.2%. Cancellation rate 1.50% of 74,759 scheduled flights, 2024 to 2025.
Why CVG runs the way it does
No single carrier dominates CVG. The largest carriers in this window, by departures, are Delta Air Lines (19.6%), Republic Airways (12.8%) and Endeavor Air (11.9%), so the airport's record reflects several operations rather than one hub schedule.
CVG delays peak in July (28.7%), June (24.0%) and January (21.0%) and are lowest in October (13.9%). That shape is consistent with the summer thunderstorm season, when convective weather builds through the afternoon and slows arrivals and departures.
Delays build through the day: 12.8% of flights scheduled before 8 AM ran late against 31.8% after 8 PM. That is the pattern BTS describes as late-arriving aircraft, where a previous flight with the same aircraft arriving late makes the next departure late.
