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

HNL in April lands a B+, 3 points better than the national rate of 79.8%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 4,809 flights, of which United Airlines flew 411 at 90.1% on time.

United Airlines is the most reliable of the three carriers covered here at 90.1% on time across 411 flights.

HNL across all twelve months

These figures cover 4,809 departures from Daniel K. Inouye 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 HNL's other months

Against HNL's own year, April ran level with the twelve-month rate of 82.9%, which makes it number seven of twelve months, best first. Either side of it, March ran 73.7% on time and May 82.7%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave HNL in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am602 flights92.3%
  • 8am–11am678 flights88.8%
  • 11am–2pm1,185 flights72.3%
  • 2pm–5pm826 flights77.6%
  • 5pm–8pm620 flights85.7%
  • 8pm–5am898 flights88.8%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 72.3% on time against 92.3% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 1,185 flights scheduled in it.

Across the week, Monday is the strongest day at 86.4% on time and Friday the weakest at 79.8%. 7 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at HNL in April

The choice of carrier is not cosmetic here. United Airlines arrives on time 90.1% of the time; Alaska Airlines manages 78.0%. Sample sizes sit next to every figure, because a two-point gap across 2,805 flights means less than a ten-point one.

The spread between United and Alaska is 12 points, wide enough that it should decide the booking. On a hundred trips that is 12 more arrivals inside the on-time window.

Delay causes

What held HNL up in April

One category carries most of the weight here. Carrier accounts for 59% of the 39,000 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.

  • Carrier
    59%
  • Late-arriving aircraft
    26%
  • National Airspace System
    13%
  • Extreme weather
    1%
  • Security
    0%

The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 23,000 of the 39,000 delay minutes reported here. The split is drawn from 38,546 reported delay minutes.

Cancellations are rare at 0.60%, 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 3.1% 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 HNL in April

For a April trip through HNL: expect 82.8% on time and 0.60% cancelled, going by April 2026. The 5am–8am window was the strongest part of the day.
