These figures cover 559 flights between September 2025 and August 2026. The median arrival is 10 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
SkyWest against every carrier on SLC to LGB
SkyWest flew 559 of the 1,569 flights on SLC to LGB, about 36% of it. Its 92.7% on time is 7 points better than the route as a whole, which runs 86.2%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 92.7% to Southwest at 76.6%.

| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SkyWest Airlines (this page) | 559 | 92.7% | 51 min | 0.00% | A+ |

| Southwest Airlines | 480 | 76.6% | 42 min | 0.21% | B+ |
Delta leads Southwest by 12 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 66% of the 2,073 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Carrier
- 28%Extreme weather
- 6%National Airspace System
Extreme weather accounts for 28% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.6 times the usual weather exposure. The split is drawn from 2,073 reported delay minutes.
The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,377 of the 2,073 delay minutes reported here.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 1.8% land an hour or more behind schedule, against 8.3% 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.
The 588 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 92.1% on time across 560 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 559 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking SkyWest on SLC to LGB
Put together: treat all of this as provisional. 559 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 92.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 559 completed flights over 12 months sit behind that.
