Why PHX → LAS flights are cancelled

July 2023 – July 2026

PHX → LAS cancelled 170 of 20,519 scheduled flights — about 1 in every 121. The reason filed most often was the airline, 41.8% of the cancellations coded on this route — about 1 in every 289 scheduled flights.

Of 170 cancelled departures carrying a reason code.

What each reason means

The airline1 in 289

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

71 cancellations, 41.8% of the total.

Extreme weather1 in 360

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

57 cancellations, 33.5% of the total.

The air traffic system1 in 489

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

42 cancellations, 24.7% 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.

170 coded cancellations were recorded on PHX → LAS; the section appears from 50.

Will your connection be tight enough?

Layovers at LAS after arriving from PHX.

Connection buffer and chance of missing by layover length, PHX → LAS arrivals
Connection time	Chance of missing	Reads as
30 min	38%	Likely to miss
45 min	21%	High risk
60 min	14%	Some risk
90 min	7.4%	Some risk
120 min	4.1%	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 0.83% 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 20,338 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 20,519 operations.

Why PHX → LAS runs late

July 2023 – July 2026

Late-arriving aircraft51.0%

the inbound aircraft was late, so this flight started late

The airline26.8%

crew, maintenance, boarding and fueling, all within the carrier’s control

Air traffic control19.9%

airspace and airport capacity, including weather-driven flow control

Weather2.1%

Security0.2%

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

Late-arriving aircraft is the largest cause on PHX → LAS, at 51.0%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 92.9% of the time and 3–6 PM departures 66.8%.

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 3.9 times the normal rate at PHX against 2.4 times at LAS. Cancelled in bad weather against normal hours: PHX 2.5% against 0.6%, LAS 2.0% against 0.8%. Flights that did leave PHX in bad weather arrived on time 53.7% of the time, against 80.6% in normal hours.
