This route carries a cancellation problem, not just a delay problem: 6.7% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 743 LGA to OKC flights, with a median arrival 7 minutes early.
Best time to fly LGA to OKC: a 5am–8am departure, ideally on a Saturday. Flights in that window arrived on time 82.3% of the time and Saturday flights 86.2%, against 71.7% for the route overall.
The national on-time rate over the same period is 77.3%, so this route runs 6 points behind the country as a whole. Across a thousand flights that is about 56 extra late arrivals.

The 5pm–8pm window is where this operation falls apart: 61.9% on time, against 82.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 371 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 37 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.
December is the weak month at 54.3% on time, against 91.7% in April. 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. October was the busiest month here, with 88 flights.
Across the week, Saturday is the strongest day at 86.2% on time and Thursday the weakest at 63.8%, a spread of 22 points.
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 16,000 reported delay minutes.
- 35%Late-arriving aircraft
- 30%National Airspace System
- 27%Carrier
- 7%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 15,888 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 82.3% on time here.
Cancellations run at 6.73%, against 1.89% nationally. That is about one flight in fifteen 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
12.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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.
The return leg is a different operation and performs like one: it runs 79.4% on time across 743 flights, 8 points above 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 8 points of difference.
One caution: this is a thin sample. 743 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 6.73% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 683 completed flights over 12 months sit behind that.
Common questions
LGA to OKC questions
How often is LGA to OKC delayed?
Roughly one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 28.3% of the 743 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is LGA to OKC compared with the rest of the country?
71.7% of flights arrive on time here against a national 77.3%, a difference of 6 points against it. That is worth a C− on this site's grading scale.
What time of day has the fewest delays on LGA to OKC?
The 5am–8am departure window is the strongest at 82.3% on time. The 5pm–8pm window is the weakest at 61.9%, 20 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 December delays on LGA to OKC?
December is the weakest month at 54.3% on time, compared with 91.7% in April. Across the year that is 37 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
