DOT / BTS on-time filings

Know which flights actually land on time.

Airline and route reliability scored from the U.S. Department of Transportation's on-time performance filings — the same figures carriers are required to report. Historical, cited, and free.

A flight is “on time” until it is

+15 min

Measured at the gate, not the wheels. Arrive 14 minutes late and the flight counts as on time; 15 and it counts as delayed. Every index here uses that federal rule, unchanged. Bureau of Transportation Statistics →

Every figure traces to a Bureau of Transportation Statistics filing, with the months and carriers it came from named on the page.

Historical performance only — no live tracking, and no predictions dressed up as data.
