Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on OKC to LGA lands a B−, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 634 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on OKC to LGA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on OKC to LGA
Republic flew 634 of the 743 flights on OKC to LGA, most of the route. Its 78.1% on time is about level with the route as a whole at 79.4%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from SkyWest at 86.2% to Republic at 78.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

Departure window
When Republic runs best on this route
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.
- 5am–8am285 flights85.6%
- 8am–11am111 flights91.4%
- 11am–2pm97 flights59.1%
- 2pm–5pm58 flights69.6%
- 5pm–8pm83 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 91.4% 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 285 flights scheduled in it.
Across the year
Republic on OKC to LGA through the year
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. October was the busiest month here, with 57 flights.
Across the week, Wednesday is the strongest day at 85.4% on time and Thursday the weakest at 73.1%, a spread of 12 points.

The worst days
Worst days for Republic on OKC to LGA
The latest arrival of the period was on 7 August 2026, 19 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 19 hours 34 minutes | Late-arriving aircraft |
| 8 June 2026 | 18 hours 19 minutes | Carrier |
| 10 July 2026 | 18 hours 19 minutes | Carrier |

Delay causes
Why Republic runs late on this route
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 14,000 reported delay minutes.
- 39%Late-arriving aircraft
- 31%Carrier
- 26%National Airspace System
- 5%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 14,207 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 91.4% on time here.
Cancellations run at 5.84%, against 1.89% nationally. That is roughly 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 costs
10.3% 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 73.2% on time across 634 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 634 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 Republic on OKC to LGA
Put together: the delay figures matter less here than the 5.84% 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. 590 completed flights over 12 months sit behind that.
