Why OAK → LAS flights are cancelled
July 2023 – July 2026

Share of cancellations
Of 91 cancelled departures carrying a reason code.
What each reason means
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
39 cancellations, 42.9% of the total.
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
37 cancellations, 40.7% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
15 cancellations, 16.5% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. With only one or two carriers on the route, the split mostly reflects how they file. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
91 coded cancellations were recorded on OAK → LAS; the section appears from 50.

Will your connection be tight enough?
Layovers at LAS after arriving from OAK.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 40% | Likely to miss |
| 45 min | 21% | High risk |
| 60 min | 13% | Some risk |
| 90 min | 6.3% | Some risk |
| 120 min | 3.4% | Low risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 0.70% of the time and diverts 0.05% of the time, which a late arrival never shows up in.
Chance of missing is the share of 12,905 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 40 minutes late (90th-percentile gate arrival delay), over 13,003 operations.

Why OAK → LAS runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for OAK → LAS. Only delays of 15 minutes or more are attributed.
Late-arriving aircraft is the largest cause on OAK → LAS, at 42.8%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 94.0% of the time and 9 PM–5 AM departures 67.7%.
