These figures cover 329 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.

Delay causes
Why OO 4084 runs late
Carrier accounts for 93% of the 962 delay minutes carriers reported here, and the remaining four split what is left.
- 93%Carrier
- 4%Extreme weather
- 3%National Airspace System
The largest share of delay minutes, 93%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 897 of the 962 delay minutes reported here. The split is drawn from 962 delay minutes reported on OO 4084.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 0.9% 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 same number turns up on one other city pair in the data, including ABQ to SLC (166), but none flew often enough under OO 4084 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to ABQ only.
One caution: this is a thin sample. 329 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 4084
For a booking, OO 4084 has one of the better records a US domestic flight can show: 93.9% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
