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 9 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 930 OKC to LAX flights, with a median arrival 10 minutes early.
Best time to fly OKC to LAX: a 8pm–5am departure, ideally on a Wednesday. Flights in that window arrived on time 91.1% of the time and Wednesday flights 88.9%, against 86.4% for the route overall.
Set against the rest of the country, this route's record is 9 points better than the US average of 77.3%. That gap is worth roughly 91 fewer late arrivals for every thousand flights.

These figures cover 930 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.

Across the year
When delays peak on this route
This route's year swings by 20 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.
Delays peak in October, when the on-time rate falls to 78.8%. June is the strongest month at 98.3%. Moving a flexible trip across that boundary buys 20 points. December was the busiest month here, with 99 flights.
Across the week, Wednesday is the strongest day at 88.9% on time and Sunday the weakest at 81.5%, a spread of 7 points.
Delay causes
Why this route gets delayed
Carrier accounts for 56% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 34%Late-arriving aircraft
- 6%National Airspace System
- 4%Extreme weather
- 1%Security
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 10,242 reported delay minutes.
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,741 of the 10,000 delay minutes reported here.
Cancellations sit at 0.97% against a national 1.89%, which is ordinary. Diversions add another 0.11%.
Connections and stage length
What a delay here actually costs
5.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
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 86.8% on time across 929 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. 930 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. 930 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 86.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 920 completed flights over 12 months sit behind that.
Common questions
OKC to LAX questions
How often is OKC to LAX delayed?
About one flight in seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.6% of the 930 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
How reliable is OKC to LAX compared with the rest of the country?
86.4% of flights arrive on time here against a national 77.3%, a difference of 9 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on OKC to LAX?
The 8pm–5am departure window is the strongest at 91.1% on time. The 5pm–8pm window is the weakest at 74.3%, 17 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 October delays on OKC to LAX?
October is the weakest month at 78.8% on time, compared with 98.3% in June. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
