SLC across all twelve months

These figures cover 9,197 departures from Salt Lake City International in November 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Either side of it, October ran 85.7% on time and December 83.8%, so this month sits in line with its neighbours.

Departure window

The best time of day to leave SLC in November

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 9,197 flights.

5am–8am812 flights91.0%
8am–11am1,778 flights88.7%
11am–2pm1,798 flights85.1%
2pm–5pm1,731 flights84.3%
5pm–8pm1,146 flights84.3%
8pm–5am1,932 flights87.3%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 91.0% on time for the 5am–8am window against 84.3% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 8pm–5am window is the busiest, with 1,932 flights scheduled in it.

Across the week, Tuesday is the strongest day at 93.4% on time and Sunday the weakest at 76.6%. 17 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at SLC in November

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 91.4% of the time; American Airlines manages 80.6%. Sample sizes sit next to every figure, because a two-point gap across 366 flights means less than a ten-point one.

SkyWest leads American by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held SLC up in November

One category carries most of the weight here. Carrier accounts for 43% of the 86,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier

National Airspace System
26%
Late-arriving aircraft

Extreme weather

Security
0%

The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 37,000 of the 86,000 delay minutes reported here. The split is drawn from 86,258 reported delay minutes.

Cancellations sit at 1.72% against a national 2.49%, which is ordinary. Diversions add another 0.21%.

Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 7.8% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
