Every carrier on LAX to GEG, 857 flights
These figures cover 624 flights between July 2025 and June 2026. The median arrival is 11 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 LAX to GEG
SkyWest flew 624 of the 857 flights on LAX to GEG, most of the route. Its 89.2% on time is about level with the route as a whole at 90.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Allegiant at 94.4% to SkyWest at 89.2%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 11 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am32 flights96.9%
- 11am–2pm229 flights92.1%
- 2pm–5pm53 flights90.6%
- 5pm–8pm255 flights85.8%
- 8pm–5am55 flights87.3%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 96.9% of the time, against 85.8% for the evening window. That is 11 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 255 flights scheduled in it.
Across the year
SkyWest on LAX to GEG through the year
Delays peak in April, when the on-time rate falls to 83.3%. June is the strongest month at 96.2%. Moving a flexible trip across that boundary buys 13 points. June was the busiest month here, with 78 flights.
Across the week, Wednesday is the strongest day at 93.1% on time and Sunday the weakest at 83.5%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 74% of the 4,574 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.
- 74%Carrier
- 10%Extreme weather
- 9%National Airspace System
- 7%Late-arriving aircraft
The largest share of delay minutes, 74%, 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 3,370 of the 4,574 delay minutes reported here. The split is drawn from 4,574 reported delay minutes.
Cancellations are rare at 0.32%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is 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 3.5% land an hour or more behind schedule, against 8.1% 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 945 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 91.0% on time across 625 flights, within 2 points 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. 624 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 LAX to GEG
Put together: treat all of this as provisional. 624 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 89.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 621 completed flights over 12 months sit behind that.
