The categories are the carriers' own reports to BTS; weather that slows the wider system is usually recorded under the National Aviation System rather than extreme weather.
What time of day has the highest on-time share from DAL?
Too few departure hours carry enough flights on this route to compare them.
Is it getting better?
The route does not have enough flights in the previous 12 months for a year-on-year comparison. The monthly chart on this page shows the months that are available.
Where does this data come from?
Every figure is computed from the Bureau of Transportation Statistics Reporting Carrier On-Time Performance files, which list each scheduled domestic flight by the carriers required to report. This page covers August 2023 to July 2026. It shows totals and averages only; it is not a live flight-status service.
