These figures cover 255 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.

Delay causes
Why OO 3708 runs late
Carrier accounts for 96% of the 1,494 delay minutes carriers reported here, and the remaining four split what is left.
- 96%Carrier
- 4%National Airspace System
The largest share of delay minutes, 96%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,441 of the 1,494 delay minutes reported here. The split is drawn from 1,494 delay minutes reported on OO 3708.
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 2.4% 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 618 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 GFK to MSP (92), but none flew often enough under OO 3708 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EUG 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 3708
For a booking, OO 3708 has one of the better records a US domestic flight can show: 93.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
