Departure window

The best time of day to leave SLC in February

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am884 flights94.3%
8am–11am1,919 flights87.6%
11am–2pm1,795 flights82.3%
2pm–5pm1,677 flights81.9%
5pm–8pm1,204 flights83.2%
8pm–5am1,688 flights87.2%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 94.3% of the time, against 81.9% for the afternoon window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 1,919 flights scheduled in it.

Across the week, Friday is the strongest day at 89.2% on time and Wednesday the weakest at 74.4%. 15 points is a smaller lever than departure hour, but it is free.

Delay causes

What held SLC up in February

One category carries most of the weight here. Carrier accounts for 42% of the 95,000 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
42%
Late-arriving aircraft
26%
National Airspace System
17%
Extreme weather
14%
Security
0%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the comparison with the other months below is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 95,496 reported delay minutes.

Cancellations sit at 0.99% against a national 2.25%, which is ordinary. Diversions add another 0.24%.

Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 6.5% 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.
