These figures cover 310 flights between September 2025 and August 2026. The median arrival is 9 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 5307
The latest arrival of the period was on 31 May 2026, 9 hours 26 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 31 May 2026 | 9 hours 26 minutes | Late-arriving aircraft |
| 7 March 2026 | 6 hours 34 minutes | Carrier |
| 27 December 2025 | 4 hours 18 minutes | Carrier |

Delay causes
Why OO 5307 runs late
Carrier accounts for 52% of the 3,106 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 37%Late-arriving aircraft
- 8%Extreme weather
- 3%National Airspace System
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,106 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 3,106 delay minutes reported on OO 5307.
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 4.8% 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 same number turns up on two other city pairs in the data, including LEX to ORD (55) and LAX to SLC (21), but none flew often enough under OO 5307 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FAT to LAX only.
One caution: this is a thin sample. 310 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 5307
For a booking, OO 5307 has one of the better records a US domestic flight can show: 88.4% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
