Why LAS → DFW flights are cancelled

July 2023 – July 2026

LAS → DFW cancelled 372 of 17,679 scheduled flights — about 1 in every 48. The reason filed most often was extreme weather, 79.8% of the cancellations coded on this route — about 1 in every 60 scheduled flights.

What each reason means

Extreme weather1 in 60

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

297 cancellations, 79.8% of the total.

The airline1 in 268

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

66 cancellations, 17.7% of the total.

The air traffic system1 in 1,964

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

9 cancellations, 2.4% 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.

Will your connection be tight enough?

Layovers at DFW after arriving from LAS.

Connection buffer and chance of missing by layover length, LAS → DFW arrivals
Connection time	Chance of missing	Reads as

60 min	15%	Some risk
90 min	8.5%	Some risk
120 min	5.6%	Some 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 2.10% of the time and diverts 0.48% of the time, which a late arrival never shows up in.

Chance of missing is the share of 17,222 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 51 minutes late (90th-percentile gate arrival delay), over 17,679 operations.

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

Late-arriving aircraft is the largest cause on LAS → DFW, at 45.9%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 86.4% of the time and 3–6 PM departures 64.7%.

How this route holds up in bad weather

July 2023 – July 2026

The harder-hit end is DFW, where the flight lands. Its figure counts departures from DFW, so it says more about how that airport copes than about this route. Bad weather cancels 7.0 times the normal rate at DFW against 2.4 times at LAS. Cancelled in bad weather against normal hours: LAS 2.0% against 0.8%, DFW 10.4% against 1.5%. Flights that did leave LAS in bad weather arrived on time 58.5% of the time, against 78.5% in normal hours.
