Honolulu, Oahu (HNL) and Kahului (OGG): July 2026 on-time record

Taken together, the two directions did well against the country in July 2026: 87.0% of the 1,606 flights between Honolulu, Oahu and Kahului arrived on time, above the national share of 69.4% across all 630,535 reported flights. That puts the pair on the favourable side of the national picture.

This pair was dominated by one operator: Alaska Airlines alone flew 70.0% of all flights, more than half.

Southwest Airlines came out clearly on top: it had the highest on-time share in both directions, and each lead over the next airline was large enough to separate in one month of data. This is the one airline whose edge the figures support.

No single cause clearly led the delay minutes BTS attributed to flights between Honolulu, Oahu and Kahului: Late-arriving aircraft at 41.2% and Air carrier at 41.4% were within 5 points of each other, unlike the national total for July 2026, where Late-arriving aircraft led.

Neither direction stood out: 86.9% of flights from Honolulu, Oahu and 87.2% of flights from Kahului arrived on time, within a few points of each other, which one month of data cannot separate. Treat the two directions as one record.

2 airlines flew this pair often enough to be ranked in at least one direction. Each is set against the pair's combined figure below, so the comparison is among a small field.

Alaska Airlines dominated this pair, flying more than half of all its flights, 1,124 in all, and 84.0% of them arrived on time, level with the pair's combined 87.0%, give or take a few points. Every other airline here was a junior partner.

With at least a quarter of the pair's flights, Southwest Airlines put 94.2% of its 482 on time, ahead of the pair's combined 87.0%.

Of the 5 routes out of HNL that carried at least 300 flights in July 2026, the route to OGG placed in the top third for on-time arrivals.

Fewer than three routes out of OGG carried at least 300 flights in July 2026, so the route to HNL is not placed against the airport's other routes.

The two directions disagreed on the leading cause: Air carrier led on flights from Honolulu, Oahu, while Late-arriving aircraft led on flights from Kahului.

With no single cause clearly in front, only 0.0% of the attributed minutes for flights between Honolulu, Oahu and Kahului came from extreme weather, under half its national share of 6.4%.

With the leading causes close together, air carrier delays outweighed NAS delays for flights between Honolulu, Oahu and Kahului, 41.4% against 17.3% of the attributed minutes, the same order as the national figures.

Air carrier supplied 41.4% of the attributed delay minutes for flights between Honolulu, Oahu and Kahului, a clear lead but short of a near-majority, with the rest spread over the other causes. Another cause ran within 5 points of it, so the lead is not clear.

Second on the list, late-arriving aircraft added 41.2% of the attributed delay minutes for flights between Honolulu, Oahu and Kahului.

Delay causes are shares of the delay minutes BTS attributes to flights that arrived 15 minutes or more late, not shares of flights. Extreme weather here means BTS's extreme-weather category only; milder weather delays are generally reported under NAS.

A flight counts as on time unless it arrives 15 minutes or more late. Cancelled and diverted flights count as not on time.

Directions are shown only with at least 500 flights, and an airline is ranked only with at least 100 flights in a direction; airlines below that are listed by name, not ranked.

A difference of a few points between two airlines, or between two directions, is within what one month of data can move. These figures describe July 2026 only.

These are figures for one month, July 2026, not a trend or forecast.
