These figures cover 255 flights between September 2025 and August 2026. The median arrival is 14 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 3769 runs late

Carrier accounts for 58% of the 1,769 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    58%
  • Extreme weather
    41%
  • National Airspace System
    0%

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 6.9 times the usual weather exposure. The split is drawn from 1,769 delay minutes reported on OO 3769.

Cancellations are rare at 0.39%, 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 2.8% 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 575 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 one other city pair in the data, including SEA to BZN (105), but none flew often enough under OO 3769 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MFR to SLC only.

One caution: this is a thin sample. 255 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 3769

For a booking, OO 3769 has one of the better records a US domestic flight can show: 93.3% on time and 0.39% cancelled. That is a base rate, not a promise about any single day.
