Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on LGA to BNA carries a cancellation problem, not just a delay problem: 5.9% 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 1,657 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 450 at 70.3% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on LGA to BNA 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 LGA to BNA
Republic flew 1,657 of the 3,785 flights on LGA to BNA, about 44% of it. Its 74.4% on time is 4 points better than the route as a whole, which runs 70.3%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Republic at 74.4% to SkyWest at 57.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Southwest Airlines cancels 4.5% 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.

Departure window
When Republic runs best on this route

- 8am–11am444 flights82.7%
- 11am–2pm303 flights76.2%

Scale runs 55% to 90%.
The 8pm–5am window is where this operation falls apart: 62.6% on time, against 86.7% 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 444 flights scheduled in it.
Across the year
Republic on LGA to BNA through the year
December is the weak month at 60.7% on time, against 84.5% in September. 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. March was the busiest month here, with 223 flights.
Across the week, Saturday is the strongest day at 78.6% on time and Sunday the weakest at 70.3%, a spread of 8 points.

Share of 1,555 completed flights by arrival against schedule.
53 of 343 late departures made up the time and arrived on time, 15% of them. In the other direction, 108 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 BNA.
The worst days
Worst days for Republic on LGA to BNA
The latest arrival of the period was on 6 July 2026, 5 hours 27 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across July, August, June and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 July 2026 | 5 hours 27 minutes | Carrier |
| 7 August 2026 | 5 hours 8 minutes | National Airspace System |
| 23 June 2026 | 5 hours 1 minute | Late-arriving aircraft |
| 11 March 2026 | 4 hours 22 minutes | Extreme weather |
| 24 March 2026 | 4 hours 6 minutes | Late-arriving aircraft |
Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 49% of the 25,000 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 25%National Airspace System
- 22%Carrier
- 4%Extreme weather
- 0%Security
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 25,000 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 25,019 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 86.7% on time here.
Cancellations run at 5.91%, 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
9.5% 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 764 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 runs 73.7% on time across 1,658 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,657 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 BNA
Put together: the delay figures matter less here than the 5.91% 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. 1,555 completed flights over 12 months sit behind that.
