This route earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 858 GEG to LAX flights, with a median arrival 11 minutes early.
Best time to fly GEG to LAX: a 5am–8am departure, ideally on a Sunday. Flights in that window arrived on time 92.6% of the time and Sunday flights 94.9%, against 91.3% for the route overall.
Set against the rest of the country, this route's record is 14 points better than the US average of 77.6%. That gap is worth roughly 137 fewer late arrivals for every thousand flights.

These figures cover 858 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
Which airline is most reliable on GEG to LAX
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.

Flight by flight
Flights on GEG to LAX
The flight numbers below flew this route at least 250 times in the period, busiest first. Each has its own record, with its schedule and delay causes.
Departure window
The best time of day to leave
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 858 flights.
- 5am–8am477 flights92.6%
- 8am–11am2 flights—
- 11am–2pm23 flights—
- 2pm–5pm242 flights89.6%
- 5pm–8pm114 flights90.0%
- 8pm–5am—
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
The 5am–8am window is the strongest at 92.6% on time. The full set of windows spans 3 points.
Across the year
When delays peak on this route
This route's year swings by 14 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
December is the weak month at 82.5% on time, against 96.7% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. June was the busiest month here, with 108 flights.
Across the week, Sunday is the strongest day at 94.9% on time and Friday the weakest at 84.6%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 62% of the 6,429 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.
- 62%Carrier
- 17%Late-arriving aircraft
- 13%Extreme weather
- 6%National Airspace System
- 1%Security
Extreme weather accounts for 13% 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 2.2 times the usual weather exposure. The split is drawn from 6,429 reported delay minutes.
The largest share of delay minutes, 62%, 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 4,015 of the 6,429 delay minutes reported here.
Cancellations are rare at 0.70%, 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 actually costs
Badly late arrivals are rare here: only 2.7% 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 90.5% on time across 857 flights, within about 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. 858 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 this route
Put together: treat all of this as provisional. 858 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 91.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 852 completed flights over 12 months sit behind that.
Common questions
GEG to LAX questions
How often is GEG to LAX delayed?
About one flight in twelve arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 8.7% of the 858 flights in this analysis, against 22.4% nationally. Delayed flights are late by an hour and a half on average.
How reliable is GEG to LAX compared with the rest of the country?
91.3% of flights arrive on time here against a national 77.6%, a difference of 14 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on GEG to LAX?
The 5am–8am departure window is the strongest at 92.6% on time. The 2pm–5pm window is the weakest at 89.6%, 3 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on GEG to LAX?
December is the weakest month at 82.5% on time, compared with 96.7% in September. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
