Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Alaska Airlines.
Alaska on SEA to OGG lands a B+, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That rests on 1,322 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Alaska on SEA to OGG from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on SEA to OGG, 1,809 flights
These figures cover 1,322 flights between September 2025 and August 2026. The median arrival is 6 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Alaska against every carrier on SEA to OGG
Alaska flew 1,322 of the 1,809 flights on SEA to OGG, most of the route. Its 78.2% on time is about level with the route as a whole at 79.2%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 86.0% to Hawaiian at 70.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Alaska runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 1,322 flights.
- 5am–8am—
- 8am–11am607 flights78.6%
- 11am–2pm295 flights77.9%
- 2pm–5pm70 flights81.2%
- 5pm–8pm350 flights77.2%
- 8pm–5am—
Scale runs 70% to 85%. Rows with fewer than 30 flights show a dash.
The 2pm–5pm window is the strongest at 81.2% on time. The full set of windows spans 4 points.
Across the year
Alaska on SEA to OGG through the year
December is the weak month at 69.9% on time, against 90.0% in June. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 124 flights.
Across the week, Wednesday is the strongest day at 84.1% on time and Friday the weakest at 74.7%, a spread of 9 points.
Arrival by arrival
How late Alaska on SEA to OGG runs when it is late

Share of 1,306 completed flights by arrival against schedule.
A late pushback is often recovered here: of 258 departures that left 15 minutes late or more, 96 still arrived on time. In the other direction, 123 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at OGG.
The worst days
Worst days for Alaska on SEA to OGG
The latest arrival of the period was on 28 December 2025, 5 hours 46 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 5 hours 46 minutes | Carrier |
| 18 July 2026 | 5 hours 9 minutes | Carrier |
| 13 March 2026 | 5 hours 8 minutes | Extreme weather |
| 10 August 2026 | 4 hours 35 minutes | Carrier |

Delay causes
Why Alaska runs late on this route
Carrier accounts for 53% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 24%National Airspace System
- 18%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,993 of the 13,000 delay minutes reported here. The split is drawn from 13,172 reported delay minutes.
Cancellations are rare at 0.61%, below the national 1.89% 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.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.3% 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.
At 2,639 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg runs 79.3% on time across 1,322 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,322 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking Alaska on SEA to OGG
Put together: the calendar is the biggest lever here, not the carrier or the hour. June runs 90.0% on time and December 69.9%, a swing of 20 points. If the dates move at all, move them out of December before you think about anything else. 1,306 completed flights over 12 months sit behind that.
