These figures cover 365 flights between September 2025 and August 2026. The median arrival is 11 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.

The worst days
Worst days for OO 4649
The latest arrival of the period was on 24 December 2025, 6 hours 49 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 December 2025 | 6 hours 49 minutes | Carrier |
| 6 October 2025 | 6 hours 38 minutes | Carrier |
| 25 December 2025 | 5 hours 30 minutes | National Airspace System |

Delay causes
Why OO 4649 runs late
Carrier accounts for 57% of the 3,693 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 27%Extreme weather
- 13%National Airspace System
- 4%Late-arriving aircraft
Extreme weather accounts for 27% 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 4.5 times the usual weather exposure. The split is drawn from 3,693 delay minutes reported on OO 4649.
Cancellations are rare at 0.55%, 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
5.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
Every one of the 365 flights under OO 4649 in the data flew SBA to LAX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 4649
For a booking, OO 4649 has one of the better records a US domestic flight can show: 90.3% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
