These figures cover 361 flights between July 2025 and June 2026. The median arrival is 16 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When OO 5492 flies

OO 5492 flies FSD to DEN without a single fixed slot. Its most common scheduled departure was 13:40, used on 57 of 361 flights, with 14:00 (49 flights) and 14:08 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 13:40 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5492 runs 11 points better at 89.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Delay causes

Why OO 5492 runs late

One category carries most of the weight here. National Airspace System accounts for 44% of the 4,467 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
27%
Carrier

Extreme weather
5%

44% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,979 minutes out of 4,467, against a national NAS share of 21%. The split is drawn from 4,467 delay minutes reported on OO 5492.

Cancellations are rare at 0.83%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

5.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.

Every one of the 361 flights under OO 5492 in the data flew FSD to DEN. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 361 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking OO 5492

For a booking, OO 5492 has one of the better records a US domestic flight can show: 89.6% on time and 0.83% cancelled. That is a base rate, not a promise about any single day.
