Historical odds, not a guarantee. Built from the US DOT Bureau of Transportation Statistics on-time reports (Jun 2025 to May 2026), FAA ground stop and delay program advisories, and 20 years of airport weather observations. Covers US airlines that report to the DOT; schedules are flights operated recently, so confirm times when you book. ATIS Alerts is not affiliated with any airline.

Which airline is most on time from PHX to CVG?
American, with a season-adjusted 77% chance of operating and arriving on time over 467 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

June (64% on time); the best was September (91%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
