These figures cover 336 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 April 2026 | 3 hours 4 minutes | Extreme weather |
| 11 June 2026 | 2 hours 42 minutes | Late-arriving aircraft |

Delay causes
Why OO 5487 runs late
Carrier accounts for 62% of the 1,345 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 21%Late-arriving aircraft
- 14%Extreme weather
- 3%National Airspace System
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 1,345 delay minutes reported on OO 5487.
Cancellations are rare at 0.30%, 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 2.1% 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 same number turns up on three other city pairs in the data, including ORD to CHA (24), RAP to ORD (1) and CID to ORD (1), but none flew often enough under OO 5487 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to ABQ only.
One caution: this is a thin sample. 336 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 5487
For a booking, OO 5487 has one of the better records a US domestic flight can show: 91.9% on time and 0.30% cancelled. That is a base rate, not a promise about any single day.
