Which airline is most on time from DAL to BWI?
Southwest, with a season-adjusted 73% chance of operating and arriving on time over 1,827 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 (65% on time); the best was September (83%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
