What the record says about this route

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 86 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.

The season swings this route hard. In October it ran 19.8 points more punctual than in August — 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.

This route does better than its own airport. Departures from DTW overall run 7.9 points less punctual than this particular one — so whatever congestion DTW has, this route is largely escaping it.

Flights from Detroit to Des Moines are among the most dependable in the record. A route this punctual is usually a short hop between airports with slots to spare.

Which airline should you fly on this route?

Over July 2024 – July 2026, Endeavor Air arrived on time most often on DTW to DSM. Flights ran closest to schedule in October and worst in August.

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on DTW to DSM during July 2024 – July 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 →
