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

JFK in April lands a B+, 2 points better than the national rate of 79.8%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 8,254 flights, of which American Airlines flew 1,263 at 84.8% on time.

American Airlines is the most reliable of the four carriers covered here at 84.8% on time across 1,263 flights.

JFK across all twelve months

These figures cover 8,254 departures from John F. Kennedy International 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 JFK's other months

Against JFK's own year, April ran 6 points better than the twelve-month rate of 75.7%, which makes it number three of twelve months, best first. Cancellations were unusually low for JFK in April, at 0.24% against 3.06% across the year. Either side of it, March ran 76.4% on time and May 82.1%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave JFK in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,259 flights90.9%
  • 8am–11am1,489 flights85.8%
  • 11am–2pm1,345 flights86.1%
  • 2pm–5pm1,414 flights78.8%
  • 5pm–8pm1,477 flights75.9%
  • 8pm–5am1,270 flights72.7%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.9% of the time, against 72.7% for the overnight window. That is 18 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 1,489 flights scheduled in it.

Across the week, Saturday is the strongest day at 85.0% on time and Friday the weakest at 77.8%. 7 points is a smaller lever than departure hour, but it is free.

Delay causes

What held JFK up in April

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 89,000 reported delay minutes.

  • Late-arriving aircraft
    36%
  • Carrier
    32%
  • National Airspace System
    32%
  • Extreme weather
    1%
  • Security
    0%

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 89,000 reported delay minutes here, that single category outweighs weather by 36 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 88,734 reported delay minutes.

Cancellations are rare at 0.24%, below the national 0.90% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

5.2% 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 about an hour, which a normal layover absorbs.

What to do with this

Flying from JFK in April

For a April trip through JFK: this is one of the better months to be flying from here, 81.6% on time with 0.24% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
