Historical statistics for June 2026, not live status or a forecast for this year’s June. For today’s conditions at LGA, see live FAA status.
LGA in June carries a cancellation problem, not just a delay problem: 4.2% of scheduled flights never operate, against 1.6% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 10,877 flights, of which Republic Airways flew 4,714 at 80.4% on time.
Republic Airways is the most reliable of the five carriers covered here at 80.4% on time across 4,714 flights.

Departure window
The best time of day to leave LGA in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 18 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,613 flights87.5%
- 8am–11am1,946 flights86.1%
- 11am–2pm1,893 flights82.6%
- 2pm–5pm2,220 flights66.1%
- 5pm–8pm1,933 flights63.6%
- 8pm–5am1,272 flights63.8%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.6% on time, against 87.5% 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 2pm–5pm window is the busiest, with 2,220 flights scheduled in it.
Across the week, Tuesday is the strongest day at 79.2% on time and Saturday the weakest at 70.3%. 9 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at LGA in June
The choice of carrier is not cosmetic here. Republic Airways arrives on time 80.4% of the time; Southwest Airlines manages 62.6%. Sample sizes sit next to every figure, because a two-point gap across 984 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 4,714 | 80.4% | 71 min | 4.92% | B− |
| Delta Air Lines | 2,379 | 77.5% | 81 min | 2.61% | B |

| Frontier Airlinesthin sample | 180 | 53.4% | 90 min | 10.56% | F− |
Republic Airways 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.

Delay causes
What held LGA up in June
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 206,000 reported delay minutes.
- 41%Late-arriving aircraft
- 28%National Airspace System
- 24%Carrier
- 7%Extreme weather
- 0%Security
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 206,000 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 206,103 reported delay minutes.
Cancellations run at 4.16%, against 1.65% nationally. That is about one flight in 25 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.4% of arrivals land a full hour or more behind schedule, against 9.7% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
