These figures cover 351 flights between September 2025 and August 2026. The median arrival is 6 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 F9 1993 runs late
Late-arriving aircraft accounts for 54% of the 4,156 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 30%Carrier
- 14%National Airspace System
- 2%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,156 reported delay minutes here, that single category outweighs weather by 32 to one. The split is drawn from 4,156 delay minutes reported on F9 1993.
Cancellations are rare at 0.28%, 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 4.9% 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.
The 628 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 351 flights under F9 1993 in the data flew DEN to LAS. 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. 351 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
