These figures cover 276 flights between September 2025 and August 2026. The median arrival is 12 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.

The latest arrival of the period was on 9 November 2025, 13 hours 35 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across November, June, August and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 13 hours 35 minutes | Late-arriving aircraft |
| 11 November 2025 | 9 hours 49 minutes | National Airspace System |
| 1 June 2026 | 2 hours 38 minutes | Extreme weather |

Delay causes
Why F9 2341 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 2,849 reported delay minutes.
- 37%Late-arriving aircraft
- 30%National Airspace System
- 23%Carrier
- 10%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,849 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 2,849 delay minutes reported on F9 2341.
Cancellations are rare at 0.72%, 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 4.0% 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 862 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 276 flights under F9 2341 in the data flew DEN to LAX. 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. 276 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 2341
For a booking, F9 2341 has one of the better records a US domestic flight can show: 89.8% on time and 0.72% cancelled. That is a base rate, not a promise about any single day.
