These figures cover 361 flights between September 2025 and August 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.

Delay causes
Why OO 5492 runs late
National Airspace System accounts for 50% of the 2,975 delay minutes carriers reported here, and the remaining four split what is left.
- 50%National Airspace System
- 26%Late-arriving aircraft
- 17%Carrier
- 7%Extreme weather
50% 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 1,492 minutes out of 2,975, against a national NAS share of 21%. The split is drawn from 2,975 delay minutes reported on OO 5492.
Cancellations are rare at 0.83%, below the national 1.89% 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
Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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: 91.6% on time and 0.83% cancelled. That is a base rate, not a promise about any single day.
