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

EWR in June lands a B, 4 points better than the national rate of 74.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 9,967 flights, of which Republic Airways flew 2,340 at 83.4% on time.

Republic Airways is the most reliable of the five carriers covered here at 83.4% on time across 2,340 flights.

Departure window

The best time of day to leave EWR in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 7 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,657 flights91.6%
  • 8am–11am1,879 flights87.2%
  • 11am–2pm1,531 flights84.2%
  • 2pm–5pm1,678 flights71.8%
  • 5pm–8pm1,869 flights66.5%
  • 8pm–5am1,353 flights69.0%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 91.6% of the time, against 66.5% for the evening window. That is 25 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 1,879 flights scheduled in it.

Across the week, Tuesday is the strongest day at 81.8% on time and Sunday the weakest at 72.8%. 9 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at EWR in June

The choice of carrier is not cosmetic here. Republic Airways arrives on time 83.4% of the time; United Airlines manages 76.6%. Sample sizes sit next to every figure, because a two-point gap across 5,577 flights means less than a ten-point one.

Delay causes

What held EWR up in June

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 182,000 reported delay minutes.

  • Late-arriving aircraft
    37%
  • Carrier
    29%
  • National Airspace System
    29%
  • Extreme weather
    5%
  • Security
    0%

37% 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 182,000 reported delay minutes here, that single category outweighs weather by 7 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 182,434 reported delay minutes.

Cancellations sit at 1.53% against a national 1.65%, which is ordinary. Diversions add another 0.24%.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.6% of arrivals land a full hour or more behind schedule, against 9.7% 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.

What to do with this

Flying from EWR in June

For a June trip through EWR: expect 78.6% on time and 1.53% cancelled, going by June 2026. The 5am–8am window was the strongest part of the day.
