OO 3025 earns a D+, which is as low as this site's scale goes for a reason. Only 55.6% of flights arrive inside the 15-minute window, 22 points worse than the national rate of 77.3%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 278 flights, with a median arrival 10 minutes late.
The national on-time rate over the same period is 77.3%, so OO 3025 runs 22 points behind the country as a whole. Across a thousand flights that is about 217 extra late arrivals.

Across the year
OO 3025 quarter by quarter
OO 3025 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.8% on time and its weakest Jul–Sep 2026 at 21.0%, a swing of 61 points on roughly 70 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OO 3025 did best on Saturday at 72.2% on time and worst on Thursday at 42.1%. Each day rests on about 40 flights, so a gap of 30 points is worth noticing but could still narrow in another year.

Share of 268 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 101 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SFO.
The worst days
Worst days for OO 3025
The latest arrival of the period was on 8 November 2025, 4 hours 5 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 November 2025 | 4 hours 5 minutes | National Airspace System |
| 1 December 2025 | 3 hours 22 minutes | Late-arriving aircraft |
| 24 February 2026 | 2 hours 41 minutes | Carrier |
| 2 November 2025 | 2 hours 20 minutes | National Airspace System |
| 5 May 2026 | 2 hours 10 minutes | National Airspace System |
Delay causes
Why OO 3025 runs late
National Airspace System accounts for 79% of the 7,169 delay minutes carriers reported here, and the remaining four split what is left.
- 79%National Airspace System
- 14%Carrier
- 7%Late-arriving aircraft
79% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 5,662 minutes out of 7,169, against a national NAS share of 21%. The split is drawn from 7,169 delay minutes reported on OO 3025.
Cancellations are rare at 0.72%, 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
18.7% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 522 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 DEN to SAN (21), but none flew often enough under OO 3025 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOI to SFO only.
One caution: this is a thin sample. 278 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 3025
For a booking, OO 3025 is a flight to put a long connection behind. 18.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
