What the record says about this route
Which airline you fly changes the odds here. Delta Air Lines arrived on time 13.5 points more often than Southwest Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
The season swings this route hard. In February it ran 25.8 points more punctual than in July — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 76 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
This route does better than its own airport. Departures from BWI overall run 7.2 points less punctual than this particular one — so whatever congestion BWI has, this route is largely escaping it.
Which airline should you fly on this route?
Over January 2025 – August 2026, Delta Air Lines arrived on time most often on BWI to MSP. Southwest Airlines was late most often. Flights ran closest to schedule in February and worst in July.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on BWI to MSP during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
