These figures cover 259 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.

|---|---|---|
| 19 March 2026 | 2 hours 22 minutes | Carrier |
| 21 July 2026 | 1 hour 36 minutes | Extreme weather |

Delay causes
Why OO 3774 runs late
Carrier accounts for 53% of the 739 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 41%Extreme weather
- 6%National Airspace System
Extreme weather accounts for 41% 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 6.8 times the usual weather exposure. The split is drawn from 739 delay minutes reported on OO 3774.
Cancellations are rare at 0.77%, 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 1.6% 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 501 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 four other city pairs in the data, including GRR to MSP (10), MSP to GRR (10) and SJC to LAX (5), but none flew often enough under OO 3774 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to FAT only.
One caution: this is a thin sample. 259 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 3774
For a booking, OO 3774 has one of the better records a US domestic flight can show: 94.2% on time and 0.77% cancelled. That is a base rate, not a promise about any single day.
