These figures cover 292 flights between September 2025 and August 2026. The median arrival is 13 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.

8 of 44 late departures made up the time and arrived on time, 18% of them. In the other direction, 15 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at STL.
The worst days

The latest arrival of the period was on 1 December 2025, 3 hours 39 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across December, August, June and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 December 2025 | 3 hours 39 minutes | Late-arriving aircraft |
| 14 August 2026 | 3 hours 4 minutes | Extreme weather |

Delay causes
Why F9 3302 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,687 reported delay minutes.
- 28%Carrier
- 27%Late-arriving aircraft
- 26%National Airspace System
- 20%Extreme weather
Extreme weather accounts for 20% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.3 times the usual weather exposure. The split is drawn from 2,687 delay minutes reported on F9 3302.
Cancellations are rare at 0.34%, 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 4.1% 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.
The 770 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 292 flights under F9 3302 in the data flew DEN to STL. 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. 292 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 F9 3302
