Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on LGA to PBI sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land roughly 50 minutes behind schedule. That rests on 126 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,553 at 72.1% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on LGA to PBI from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on LGA to PBI, 3,199 flights
These figures cover 126 flights between July 2025 and June 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Carrier by carrier
Republic against every carrier on LGA to PBI
Republic flew 126 of the 3,199 flights on LGA to PBI, about 4% of it. Its 73.9% 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 four carriers on the route, where the range runs from Republic at 73.9% to JetBlue at 67.3%.
The three carriers here are closely matched: 5 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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways (this page)thin sample | 126 | 73.9% | 48 min | 4.76% | C− |
| Delta Air Lines | 1,553 | 72.1% | 72 min | 4.38% | C− |

| JetBlue Airways | 1,115 | 67.3% | 74 min | 4.30% | C− |
Delta Air Lines cancels 4.4% 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
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am45 flights65.1%
- 11am–2pm58 flights85.2%
- 2pm–5pm23 flights—
- 5pm–8pm—
- 8pm–5am—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 85.2% on time, ahead of 8am–11am at 65.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 58 flights scheduled in it.
Across the year
Republic on LGA to PBI through the year
- Jul–Sep 202536 flights71.0%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 73.9% on time across 126 flights.
Split by quarter, Republic on LGA to PBI logged 36 flights in Jul–Sep 2025, 27 flights in Oct–Dec 2025 and 63 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 73.9% annual figure is the one to use.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. National Airspace System accounts for 52% of the 1,436 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 52%National Airspace System
- 26%Late-arriving aircraft
- 14%Carrier
- 7%Extreme weather
52% 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 753 minutes out of 1,436, against a national NAS share of 21%. The split is drawn from 1,436 reported delay minutes.
Cancellations run at 4.76%, against 1.81% 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
7.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.
The 1,035 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 67.8% on time across 126 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 126 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 LGA to PBI
Put together: the delay figures matter less here than the 4.76% cancellation rate. A late arrival costs you roughly 50 minutes; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 115 completed flights over 12 months sit behind that.
