Historical statistics for July 2025, not live status or a forecast for this year’s July. For today’s conditions at LGA, see live FAA status.
LGA in July carries a cancellation problem, not just a delay problem: 8.8% of scheduled flights never operate, against 2.5% nationally. Of the ones that do fly, about seven flights in ten 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 11,696 flights, of which Spirit Airlines flew 452 at 76.4% on time.
Spirit Airlines is the most reliable of the seven carriers covered here at 76.4% on time across 452 flights.

These figures cover 11,696 departures from LaGuardia in July 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.
Against the year
July next to LGA's other months
Against LGA's own year, July ran 5 points worse than the twelve-month rate of 73.4%, which makes it number eight of twelve months, best first. Cancellations are where July stands out: 8.76% of scheduled departures were called off, 1.9 times the airport's rate across the year.

Departure window
The best time of day to leave LGA in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 48 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,603 flights90.4%
- 8am–11am2,187 flights85.5%
- 11am–2pm2,112 flights78.0%
- 2pm–5pm2,364 flights53.6%
- 5pm–8pm2,094 flights42.9%
- 8pm–5am1,336 flights51.1%
Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 42.9% on time, against 90.4% 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 2,364 flights scheduled in it.
Across the week, Saturday is the strongest day at 77.8% on time and Sunday the weakest at 58.7%. 19 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at LGA in July
The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 76.4% of the time; JetBlue Airways manages 59.7%. Sample sizes sit next to every figure, because a two-point gap across 403 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 4,769 | 71.3% | 89 min | 12.12% | C− |

Republic Airways cancels 12.1% 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 July
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 361,000 reported delay minutes.
- 36%Late-arriving aircraft
- 31%National Airspace System
- 23%Carrier
- 10%Extreme weather
- 0%Security
36% 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 361,000 reported delay minutes here, that single category outweighs weather by 4 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 360,662 reported delay minutes.
Cancellations run at 8.76%, against 2.45% nationally. That is about one flight in twelve 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. 17.4% of arrivals land a full hour or more behind schedule, against 12.1% 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.

Flying from LGA in July
