Why LAS → LAX flights are cancelled
July 2023 – July 2026
LAS → LAX cancelled 193 of 28,239 scheduled flights — about 1 in every 146. The reason filed most often was the airline, 59.6% of the cancellations coded on this route — about 1 in every 246 scheduled flights.
Share of cancellations
Of 193 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.
115 cancellations, 59.6% of the total.
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
46 cancellations, 23.8% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
32 cancellations, 16.6% 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. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
193 coded cancellations were recorded on LAS → LAX; the section appears from 50.

Will your connection be tight enough?
Layovers at LAX after arriving from LAS.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 38% | Likely to miss |
| 45 min | 22% | High risk |
| 60 min | 14% | Some risk |
| 90 min | 6.6% | Some risk |
| 120 min | 3.8% | 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 0.68% of the time and diverts 0.02% of the time, which a late arrival never shows up in.
Chance of missing is the share of 28,041 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 42 minutes late (90th-percentile gate arrival delay), over 28,239 operations.

By day and hour
On-time arrival rate for each weekday and scheduled departure hour, in local time at the departure airport (LAS).

Why LAS → LAX runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow 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 LAS → LAX. Only delays of 15 minutes or more are attributed.
Late-arriving aircraft is the largest cause on LAS → LAX, at 49.9%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 90.7% of the time and 9 PM–5 AM departures 67.0%.
How this route holds up in bad weather
July 2023 – July 2026
The harder-hit end is the one the flight leaves from, where a cancellation keeps it from departing at all. Bad weather cancels 2.4 times the normal rate at LAS against 1.3 times at LAX.
