What the record says about this route
Which airline you fly changes the odds here. Endeavor Air arrived on time 10.6 points more often than Republic Airways 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 55 points more punctual than in November — 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.
Cancellation, not delay, is the risk worth pricing here: 3.87% of scheduled flights never operated. A late flight still gets you there. A cancelled one leaves you rebooking, and on a route with few daily departures that can mean losing a day.
The route has been getting worse. The later months run 15.3 points less punctual than the earlier ones. A drift of that size is rarely weather; it is more often an airline adding frequencies faster than the airports can absorb them.
Which airline should you fly on this route?
Over July 2024 – July 2026, Endeavor Air arrived on time most often on LGA to DSM. Republic Airways was late most often. Flights ran closest to schedule in September and worst in June.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on LGA 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 →
