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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 857 LAX to GEG flights, with a median arrival 12 minutes early.

Best time to fly LAX to GEG: a 8am–11am departure, ideally on a Wednesday. Flights in that window arrived on time 97.2% of the time and Wednesday flights 93.3%, against 90.5% for the route overall.

Set against the rest of the country, this route's record is 13 points better than the US average of 77.6%. That gap is worth roughly 129 fewer late arrivals for every thousand flights.

These figures cover 857 flights between July 2025 and June 2026. The median arrival is 12 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 LAX to GEG

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

The best time of day to leave

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.

  • 8am–11am36 flights97.2%
  • 11am–2pm229 flights92.1%
  • 2pm–5pm114 flights92.0%
  • 5pm–8pm276 flights85.8%
  • 8pm–5am200 flights93.5%

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 97.2% 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 276 flights scheduled in it.

Twelve months, one bar each, drawn from the same 857 flights. The strip shows how much of this route's record is set by the calendar rather than by the operation.

On-time rate by calendar month85JF90M88A85M94J91J88A95S93ON88D
Darker means more delays. Figures are on-time percentages.September best, January worst

January is the weak month at 84.8% on time, against 94.5% 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, Wednesday is the strongest day at 93.3% on time and Sunday the weakest at 86.1%. 7 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 67% of the 5,651 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
    67%
  • Late-arriving aircraft
    16%
  • National Airspace System
    9%
  • Extreme weather
    8%
  • Security
    0%

The largest share of delay minutes, 67%, 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 3,797 of the 5,651 delay minutes reported here. The split is drawn from 5,651 reported delay minutes.

Cancellations are rare at 0.58%, 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 3.3% 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 91.3% on time across 858 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. 857 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. 857 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 90.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 851 completed flights over 12 months sit behind that.

Common questions

LAX to GEG questions

How often is LAX to GEG delayed?

About one flight in ten arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 9.5% of the 857 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.

How reliable is LAX to GEG compared with the rest of the country?

90.5% of flights arrive on time here against a national 77.6%, a difference of 13 points in its favour. That is worth a A+ on this site's grading scale.

What time of day has the fewest delays on LAX to GEG?

The 8am–11am departure window is the strongest at 97.2% on time. The 5pm–8pm window is the weakest at 85.8%, 11 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 January delays on LAX to GEG?

January is the weakest month at 84.8% on time, compared with 94.5% in September. Across the year that is 10 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
