OGG across all twelve months

Against the year

May next to OGG's other months

Against OGG's own year, May ran 4 points better than the twelve-month rate of 83.0%, which makes it number three of twelve months, best first. Either side of it, April ran 81.9% on time and June 87.1%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave OGG in May

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against 11 points between the best and worst carrier.

5am–8am132 flights93.2%
8am–11am300 flights91.0%
11am–2pm645 flights84.1%

Scale runs 70% to 100%.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.2% of the time, against 79.2% for the afternoon window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 645 flights scheduled in it.

Across the week, Tuesday is the strongest day at 90.6% on time and Friday the weakest at 76.6%, a spread of 14 points.

Carrier by carrier

Which airlines ran best at OGG in May

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 93.3% of the time; Alaska Airlines manages 82.4%. Sample sizes sit next to every figure, because a two-point gap across 1,272 flights means less than a ten-point one.

Southwest leads Alaska by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held OGG up in May

Late-arriving aircraft accounts for 43% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
43%
Carrier
41%
National Airspace System
15%
Extreme weather
1%

43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 43 to one. The split is drawn from 13,556 reported delay minutes.

Cancellations are rare at 0.78%, below the national 0.92% 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 2.4% land an hour or more behind schedule, against 7.1% 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.
