Across the year
OO 5452 quarter by quarter

Share of 279 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 64 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 45 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 5452
The latest arrival of the period was on 26 June 2026, 17 hours 51 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in December 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 June 2026 | 17 hours 51 minutes | Carrier |
| 21 December 2025 | 10 hours 19 minutes | Late-arriving aircraft |
| 16 November 2025 | 8 hours 3 minutes | Carrier |
| 28 December 2025 | 4 hours 49 minutes | Late-arriving aircraft |
| 19 December 2025 | 3 hours 13 minutes | Late-arriving aircraft |
Delay causes
Why OO 5452 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,581 reported delay minutes.
- 41%Carrier
- 33%National Airspace System
- 25%Late-arriving aircraft
- 2%Extreme weather
33% 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 2,482 minutes out of 7,581, against a national NAS share of 21%. The split is drawn from 7,581 delay minutes reported on OO 5452.
Cancellations are rare at 0.36%, 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
11.1% 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 same number turns up on two other city pairs in the data, including JAX to ORD (35) and SAT to DEN (21), but none flew often enough under OO 5452 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDD to SFO only.
One caution: this is a thin sample. 280 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.
