Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on BNA to LGA carries a cancellation problem, not just a delay problem: 4.7% 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 1,658 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 1,455 at 68.2% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on BNA 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 BNA to LGA
Republic flew 1,658 of the 3,785 flights on BNA to LGA, about 44% of it. Its 73.7% on time is 3 points better than the route as a whole, which runs 70.7%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from SkyWest at 81.7% to American at 65.7%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 2 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.

Delta Air Lines cancels 4.9% 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.

Share of 1,566 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 345 departures that left 15 minutes late or more, only 39 made it up before arrival. In the other direction, 106 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 LGA.
The worst days
Worst days for Republic on BNA to LGA
The latest arrival of the period was on 7 March 2026, 17 hours 20 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in March 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 March 2026 | 17 hours 20 minutes | Carrier |
| 1 July 2026 | 14 hours 52 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 30,000 reported delay minutes.
- 38%Late-arriving aircraft
- 36%National Airspace System
- 23%Carrier
- 3%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 30,000 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 30,197 reported delay minutes.
36% 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 30,000, against a national NAS share of 21%.
Cancellations run at 4.70%, against 1.89% 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 costs
11.1% 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 74.4% on time across 1,657 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 1,658 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 BNA to LGA
Put together: the delay figures matter less here than the 4.70% cancellation rate. A late arrival costs you a little over 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. 1,566 completed flights over 12 months sit behind that.
