EWR across all twelve months

These figures cover 10,358 departures from Newark Liberty 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 EWR's other months

Against EWR's own year, April ran 7 points better than the twelve-month rate of 77.7%, which makes it number two of twelve months, best first. Cancellations were unusually low for EWR in April, at 0.69% against 3.03% across the year. Either side of it, March ran 77.7% on time and May 86.4%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave EWR in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against 23 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,636 flights92.4%
  • 8am–11am2,039 flights87.4%
  • 11am–2pm1,517 flights86.3%
  • 2pm–5pm1,925 flights80.1%
  • 5pm–8pm1,984 flights81.5%
  • 8pm–5am1,257 flights82.7%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 92.4% of the time, against 80.1% for the afternoon window. That is 12 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 2,039 flights scheduled in it.

Across the week, Saturday is the strongest day at 89.8% on time and Sunday the weakest at 81.6%. 8 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at EWR in April

The choice of carrier is not cosmetic here. Republic Airways arrives on time 90.4% of the time; Spirit Airlines manages 67.8%. Sample sizes sit next to every figure, because a two-point gap across 660 flights means less than a ten-point one.

Delay causes

What held EWR 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 96,000 reported delay minutes.

  • Late-arriving aircraft
    34%
  • National Airspace System
    33%
  • Carrier
    32%
  • Extreme weather
    2%
  • Security
    0%

34% 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 96,000 reported delay minutes here, that single category outweighs weather by 21 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 95,581 reported delay minutes.

Cancellations are rare at 0.69%, 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.

Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 6.4% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

What to do with this

Flying from EWR in April

For a April trip through EWR: this is one of the better months to be flying from here, 85.0% on time with 0.69% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
