What each reason means

Extreme weather1 in 71

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

170 cancellations, 79.4% of the total.

The airline1 in 273

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

44 cancellations, 20.6% of the total.

The air traffic system—

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

0 cancellations, 0.0% 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.

214 coded cancellations were recorded on SLC → DFW; the section appears from 50.

Layovers at DFW after arriving from SLC.

Connection buffer and chance of missing by layover length, SLC → DFW arrivals
Connection time	Chance of missing	Reads as
30 min	36%	Likely to miss
45 min	21%	High risk
60 min	14%	Some risk
90 min	8.3%	Some risk
120 min	5.4%	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 1.78% of the time and diverts 0.57% of the time, which a late arrival never shows up in.

Chance of missing is the share of 11,750 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 49 minutes late (90th-percentile gate arrival delay), over 12,033 operations.

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 barely any change at SLC. Cancelled in bad weather against normal hours: SLC 0.6% against 0.6%, DFW 10.4% against 1.5%. Flights that did leave DFW in bad weather arrived on time 56.4% of the time, against 74.4% in normal hours.
