Why LAS → SNA flights are cancelled

July 2023 – July 2026

LAS → SNA cancelled 111 of 12,678 scheduled flights — about 1 in every 114. The reason filed most often was extreme weather, 47.7% of the cancellations coded on this route — about 1 in every 239 scheduled flights.

What each reason means

Extreme weather1 in 239

Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.

53 cancellations, 47.7% of the total.

The airline1 in 362

Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.

35 cancellations, 31.5% of the total.

The air traffic system1 in 551

Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.

23 cancellations, 20.7% of the total.

Security—

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.

111 coded cancellations were recorded on LAS → SNA; the section appears from 50.

Will your connection be tight enough?

Layovers at SNA after arriving from LAS.

Connection buffer and chance of missing by layover length, LAS → SNA arrivals
Connection time	Chance of missing	Reads as
30 min	34%	Likely to miss
45 min	18%	High risk
60 min	11%	Some risk
90 min	4.7%	Low risk
120 min	2.4%	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 0.88% of the time and diverts 0.13% of the time, which a late arrival never shows up in.

Chance of missing is the share of 12,550 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 33 minutes late (90th-percentile gate arrival delay), over 12,678 operations.

Share of the delay minutes US DOT attributed to each cause for LAS → SNA. Only delays of 15 minutes or more are attributed.

Late-arriving aircraft is the largest cause on LAS → SNA, at 43.0%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 91.7% of the time and 3–6 PM departures 71.8%.

How this route holds up in bad weather

July 2023 – July 2026
