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

Share of cancellations
Of 75 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
32 cancellations, 42.7% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
29 cancellations, 38.7% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
14 cancellations, 18.7% 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.
75 coded cancellations were recorded on LAS → OAK; the section appears from 50.

Will your connection be tight enough?
Layovers at OAK after arriving from LAS.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 43% | Likely to miss |
| 45 min | 24% | High risk |
| 60 min | 15% | Some risk |
| 90 min | 6.8% | Some risk |
| 120 min | 3.5% | 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 0.58% of the time and diverts 0.04% of the time, which a late arrival never shows up in.
Chance of missing is the share of 12,912 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 45 minutes late (90th-percentile gate arrival delay), over 12,992 operations.
