SAT to DAL questions
- What time of day is best to fly SAT to DAL?
- Before 9 AM: 97% of flights arrived on time, against 69% for departures 6 to 9 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
- Which airline is most on time from SAT to DAL?
- Southwest, with a season-adjusted 83% chance of operating and arriving on time over 2,717 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 (76% on time); the best was February (89%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
- No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
