This route carries a cancellation problem, not just a delay problem: 5.1% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 810 OKC to LGA flights, with a median arrival 8 minutes early.
Best time to fly OKC to LGA: a 8am–11am departure, ideally on a Saturday. Flights in that window arrived on time 91.3% of the time and Saturday flights 85.5%, against 80.8% for the route overall.
The US average over the same twelve months is 77.6%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 810 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% 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.
Carrier by carrier
Which airline is most reliable on OKC to LGA
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 OKC to LGA
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 matters more here than the choice of carrier. The gap between the best and worst window is 32 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am417 flights86.7%
- 8am–11am155 flights91.3%
- 11am–2pm97 flights59.1%
- 2pm–5pm59 flights70.2%
- 5pm–8pm82 flights63.0%
- 8pm–5am—
Scale runs 50% 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 59.1% on time against 91.3% for 8am–11am. 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 5am–8am window is the busiest, with 417 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 29 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.
April is the best month on the calendar at 90.2% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. July was the busiest month here, with 89 flights.
Across the week, Saturday is the strongest day at 85.5% on time and Friday the weakest at 77.4%. 8 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 15,000 reported delay minutes.
- 38%Carrier
- 32%Late-arriving aircraft
- 25%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 38%, 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 5,739 of the 15,000 delay minutes reported here. The split is drawn from 15,146 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.3% on time here.
Cancellations run at 5.06%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here actually costs
8.6% of arrivals land an hour or more late, close to the national 8.1%. 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 last close to two hours, which a normal layover absorbs.
The 1,341 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 is a different operation and performs like one: it runs 71.8% on time across 810 flights, 9 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 9 points of difference.
One caution: this is a thin sample. 810 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: the delay figures matter less here than the 5.06% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 765 completed flights over 12 months sit behind that.
Common questions
OKC to LGA questions
How often is OKC to LGA delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.2% of the 810 flights in this analysis, against 22.4% nationally. Delayed flights are late by close to two hours on average.
How reliable is OKC to LGA compared with the rest of the country?
80.8% of flights arrive on time here against a national 77.6%, a difference of 3 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on OKC to LGA?
The 8am–11am departure window is the strongest at 91.3% on time. The 11am–2pm window is the weakest at 59.1%, 32 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 March delays on OKC to LGA?
March is the weakest month at 61.7% on time, compared with 90.2% in April. Across the year that is 29 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.

Direction matters. OKC to LGA and LGA to OKC are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
