This route earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs a little over an hour. That rests on 929 LAX to OKC flights, with a median arrival 9 minutes early.
Best time to fly LAX to OKC: a 2pm–5pm departure, ideally on a Tuesday. Flights in that window arrived on time 89.9% of the time and Tuesday flights 89.7%, against 86.8% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 929 flights between September 2025 and August 2026. The median arrival is 9 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.

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 18 points, against half a point between the best and worst carrier.

- 11am–2pm106 flights71.7%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 71.7% on time against 89.9% for 2pm–5pm. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5pm–8pm window is the busiest, with 360 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 15 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.
October is the best month on the calendar at 94.1% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. December was the busiest month here, with 98 flights.
Across the week, Tuesday is the strongest day at 89.7% on time and Sunday the weakest at 83.1%, a spread of 7 points.
Delay causes
Why this route gets delayed
Carrier accounts for 54% of the 9,015 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 36%Late-arriving aircraft
- 8%National Airspace System
- 2%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,015 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 9,015 reported delay minutes.
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,850 of the 9,015 delay minutes reported here.
Cancellations are rare at 0.75%, below the national 1.89% 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 4.2% 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 1,187 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 86.4% on time across 930 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. 929 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. 929 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 86.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 918 completed flights over 12 months sit behind that.
Common questions
LAX to OKC questions
How often is LAX to OKC delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.2% of the 929 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
How reliable is LAX to OKC compared with the rest of the country?
86.8% of flights arrive on time here against a national 77.3%, a difference of 10 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 OKC?
The 2pm–5pm departure window is the strongest at 89.9% on time. The 11am–2pm window is the weakest at 71.7%, 18 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 April delays on LAX to OKC?
April is the weakest month at 79.4% on time, compared with 94.1% in October. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
