Why LAS → PHX flights are cancelled

July 2023 – July 2026

LAS → PHX cancelled 176 of 20,479 scheduled flights — about 1 in every 116. The reason filed most often was the airline, 43.2% of the cancellations coded on this route — about 1 in every 269 scheduled flights.

Of 176 cancelled departures carrying a reason code.

What each reason means

The airline1 in 269

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

76 cancellations, 43.2% of the total.

Extreme weather1 in 325

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

63 cancellations, 35.8% of the total.

The air traffic system1 in 553

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

37 cancellations, 21.0% 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.

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

Will your connection be tight enough?

Layovers at PHX after arriving from LAS.

Connection buffer and chance of missing by layover length, LAS → PHX arrivals
Connection time	Chance of missing	Reads as
30 min	36%	Likely to miss

60 min	13%	Some risk
90 min	6.9%	Some risk
120 min	3.9%	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 0.86% of the time and diverts 0.07% of the time, which a late arrival never shows up in.

Chance of missing is the share of 20,288 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 43 minutes late (90th-percentile gate arrival delay), over 20,479 operations.

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

Late-arriving aircraft is the largest cause on LAS → PHX, at 57.0%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 92.8% of the time and 6–9 PM departures 67.5%.

How this route holds up in bad weather

July 2023 – July 2026

The harder-hit end is PHX, where the flight lands. Its figure counts departures from PHX, so it says more about how that airport copes than about this route. Bad weather cancels 3.9 times the normal rate at PHX against 2.4 times at LAS. Cancelled in bad weather against normal hours: LAS 2.0% against 0.8%, PHX 2.5% against 0.6%. Flights that did leave PHX in bad weather arrived on time 53.7% of the time, against 80.6% in normal hours.
