SkyWest Airlines at Oklahoma City lands a B, 3 points better than the national rate of 77.4%. About one flight in five arrive 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 8,129 flights, of which Delta Air Lines flew 1,730 at 87.6% on time.
Measured against the airport rather than the country, SkyWest Airlines runs half a point behind the 80.4% weighted average across all carriers at OKC. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#4
Of 10 carriers clearing the floor at OKC
These figures cover 8,129 flights between June 2025 and May 2026. Beyond the headline rate, 8.8% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Against the competition
Every carrier at OKC, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.6% of the time; PSA Airlines manages 71.8%. Sample sizes sit next to every figure, because a two-point gap across 397 flights means less than a ten-point one.

| PSA Airlines | 397 | 71.8% | 109 min | 5.04% | C− |
PSA Airlines cancels 5.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Route by route
Where SkyWest Airlines flies from OKC
SkyWest Airlines operates 10 routes out of OKC with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is the strongest at 91.3% on time. The full set of windows spans 21 points.
Across the year
Seasonal pattern
June is the worst month at 68.6% on time, 17 points below September, the best at 85.8%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck.

The largest share of delay minutes, 59%, 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 79,000 of the 134,000 delay minutes reported here.
Cancellations sit at 1.40% against a national 1.80%, which is ordinary. Diversions add another 0.34%.
8.8% of arrivals land an hour or more late, close to the national 8.2%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route are the an hour and a half kind, which a normal layover absorbs.
The sample behind these figures is 8,129 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 85.8% on time and June 68.6%, a swing of 17 points. If the dates move at all, move them out of June before you think about anything else.
Common questions
SkyWest Airlines at OKC
How often is SkyWest Airlines at OKC delayed?
About one flight in five arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.7% of the 8,129 flights in this analysis, against 22.6% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on SkyWest Airlines at OKC?
Delta Air Lines leads at 87.6% on time across 1,730 flights. PSA Airlines is at the other end on 71.8%, a gap of 16 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on SkyWest Airlines at OKC?
The 8pm–5am departure window is the strongest at 91.3% on time. The 5pm–8pm window is the weakest at 70.3%, 21 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 June delays on SkyWest Airlines at OKC?
June is the weakest month at 68.6% on time, compared with 85.8% in September. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
