These figures cover 11,582 departures from LaGuardia in August 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
August next to LGA's other months
Against LGA's own year, August ran 8 points better than the twelve-month rate of 73.4%, which makes it number two of twelve months, best first. Cancellations were unusually low for LGA in August, at 1.79% against 4.56% across the year. Either side of it, July ran 68.0% on time and September 82.4%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave LGA in August
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 22 points, against 21 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,583 flights92.6%
- 8am–11am2,119 flights90.1%
- 11am–2pm2,090 flights85.4%
- 2pm–5pm2,402 flights72.6%
- 5pm–8pm2,088 flights70.4%
- 8pm–5am1,300 flights77.1%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.6% of the time, against 70.4% for the evening window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 2,402 flights scheduled in it.
Across the week, Tuesday is the strongest day at 86.5% on time and Thursday the weakest at 75.8%. 11 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at LGA in August
The choice of carrier is not cosmetic here. Republic Airways arrives on time 85.9% of the time; JetBlue Airways manages 65.1%. 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 | 4,701 | 85.9% | 64 min | 1.98% | A |
| Delta Air Lines | 2,485 | 82.1% | 93 min | 1.57% | B |

The spread between Republic and JetBlue is 21 points, wide enough that it should decide the booking. On a hundred trips that is 21 more arrivals inside the on-time window.

Delay causes
What held LGA up in August
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 175,000 reported delay minutes.
- 40%Late-arriving aircraft
- 32%Carrier
- 24%National Airspace System
- 4%Extreme weather
- 0%Security
40% 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 175,000 reported delay minutes here, that single category outweighs weather by 11 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 174,710 reported delay minutes.
Cancellations sit at 1.79% against a national 1.08%, which is ordinary. Diversions add another 0.56%.
7.8% of arrivals land an hour or more late, close to the national 8.2%. 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 a little over an hour, which a normal layover absorbs.
