These figures cover 348 flights between September 2025 and August 2026. The median arrival is 10 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 3729 runs late
Carrier accounts for 80% of the 1,877 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Carrier
- 16%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 16% 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 2.6 times the usual weather exposure. The split is drawn from 1,877 delay minutes reported on OO 3729.
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 2.9% 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 RIC to DTW (16), but none flew often enough under OO 3729 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. 348 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 3729
For a booking, OO 3729 has one of the better records a US domestic flight can show: 89.0% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
