These figures cover 275 flights between September 2025 and August 2026. The median arrival is 8 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 11 September 2025 | 7 hours 43 minutes | Carrier |
| 7 October 2025 | 7 hours 1 minute | Late-arriving aircraft |

Delay causes
Why UA 2493 runs late
Carrier accounts for 73% of the 3,346 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 15%National Airspace System
- 12%Late-arriving aircraft
The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,443 of the 3,346 delay minutes reported here. The split is drawn from 3,346 delay minutes reported on UA 2493.
Cancellations are rare at 0.36%, 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
6.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 1,481 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.
The same number turns up on three other city pairs in the data, including SAN to DEN (32), PDX to ORD (21) and DEN to FLL (1), but none flew often enough under UA 2493 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RIC to DEN only.
One caution: this is a thin sample. 275 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 UA 2493
For a booking, UA 2493 has one of the better records a US domestic flight can show: 86.1% on time and 0.36% cancelled. That is a base rate, not a promise about any single day.
