Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on LGA to RDU carries a cancellation problem, not just a delay problem: 5.8% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four 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 1,921 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.3%, so Republic on LGA to RDU runs 4 points behind the country as a whole. Across a thousand flights that is about 42 extra late arrivals.

Carrier by carrier
Republic against every carrier on LGA to RDU
Republic flew 1,921 of the 2,492 flights on LGA to RDU, most of the route. Its 73.1% on time is about level with the route as a whole at 71.9%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Delta at 80.8% to American at 38.6%. Three 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 41 points, against half a point between the best and worst carrier.
- 5am–8am171 flights95.1%
- 8am–11am471 flights80.5%
- 11am–2pm458 flights77.1%
- 2pm–5pm420 flights65.8%

Scale runs 45% to 100%.
The 5pm–8pm window is where this operation falls apart: 54.5% on time, against 95.1% 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 8am–11am window is the busiest, with 471 flights scheduled in it.
Across the year
Republic on LGA to RDU through the year
December is the weak month at 56.0% on time, against 85.6% in May. 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. September was the busiest month here, with 195 flights.
Across the week, Saturday is the strongest day at 80.7% on time and Sunday the weakest at 65.7%, a spread of 15 points.

Share of 1,809 completed flights by arrival against schedule.
45 of 354 late departures made up the time and arrived on time, 13% of them. In the other direction, 178 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at RDU.
The worst days
Worst days for Republic on LGA to RDU
The latest arrival of the period was on 9 November 2025, 9 hours 12 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 9 hours 12 minutes | National Airspace System |
| 30 October 2025 | 6 hours 18 minutes | Late-arriving aircraft |
| 30 October 2025 | 5 hours 23 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 46% of the 31,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 35%National Airspace System
- 16%Carrier
- 3%Extreme weather
- 0%Security
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 31,000 reported delay minutes here, that single category outweighs weather by 18 to one. The split is drawn from 30,637 reported delay minutes.
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 11,000 minutes out of 31,000, against a national NAS share of 21%.
Cancellations run at 5.78%, 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
10.2% 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.
At 431 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 69.5% on time across 1,919 flights, 4 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 4 points of difference.
The sample behind these figures is 1,921 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.
What to do with this
Booking Republic on LGA to RDU
Put together: the delay figures matter less here than the 5.78% cancellation rate. A late arrival costs you about an hour; 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. 1,809 completed flights over 12 months sit behind that.
