Historical statistics for April 2026, not live status or a forecast for this year’s April. For today’s conditions at LGA, see live FAA status.

LGA in April lands a B+, 3 points worse than the national rate of 79.8%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 11,443 flights, of which Delta Air Lines flew 2,426 at 79.3% on time.

Delta Air Lines is the most reliable of the seven carriers covered here at 79.3% on time across 2,426 flights.

LGA across all twelve months

These figures cover 11,443 departures from LaGuardia in April 2026. 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

April next to LGA's other months

Against LGA's own year, April ran 3 points better than the twelve-month rate of 73.4%, which makes it number five of twelve months, best first. Cancellations were unusually low for LGA in April, at 0.95% against 4.56% across the year. Either side of it, March ran 67.9% on time and May 75.4%, 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 April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,625 flights90.5%
8am–11am2,239 flights83.9%
11am–2pm1,901 flights82.5%
2pm–5pm2,343 flights72.4%
5pm–8pm2,031 flights64.4%
8pm–5am1,304 flights63.4%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 63.4% on time, against 90.5% 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 2,343 flights scheduled in it.

Across the week, Tuesday is the strongest day at 82.9% on time and Sunday the weakest at 57.3%. 26 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at LGA in April

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 79.3% of the time; JetBlue Airways manages 67.5%. Sample sizes sit next to every figure, because a two-point gap across 380 flights means less than a ten-point one.

Delta Air Lines	2,426	79.3%	69 min	1.07%	B

Delta leads JetBlue by 12 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held LGA up in April

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 183,000 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.

47% 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 183,000 reported delay minutes here, that single category outweighs weather by 43 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 183,403 reported delay minutes.

Cancellations sit at 0.95% against a national 0.90%, which is ordinary. Diversions add another 0.24%.

8.6% of arrivals land an hour or more late, close to the national 6.4%. 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.
