These figures cover 281 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
AS 484 quarter by quarter
AS 484 did not run the same all year. Its best quarter was Jul–Sep 2026 at 93.4% on time and its weakest Oct–Dec 2025 at 55.7%, a swing of 38 points on roughly 70 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, AS 484 did best on Tuesday at 87.2% on time and worst on Saturday at 65.8%. Each day rests on about 40 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Share of 272 completed flights by arrival against schedule.
A late pushback is often recovered here: of 56 departures that left 15 minutes late or more, 17 still arrived on time. In the other direction, 24 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 SAN.
The worst days
Worst days for AS 484
The latest arrival of the period was on 15 January 2026, 2 hours 30 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across January, March, December and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 January 2026 | 2 hours 30 minutes | Late-arriving aircraft |
| 14 March 2026 | 2 hours 22 minutes | Carrier |
| 28 December 2025 | 2 hours 20 minutes | Late-arriving aircraft |
| 16 March 2026 | 2 hours 4 minutes | Extreme weather |
| 8 May 2026 | 1 hour 57 minutes | Carrier |
Delay causes
Why AS 484 runs late
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 2,462 reported delay minutes.
- 33%Late-arriving aircraft
- 28%National Airspace System
- 24%Carrier
- 15%Extreme weather
Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 2,462 delay minutes reported on AS 484.
Cancellations sit at 2.14% against a national 1.89%, which is ordinary. Diversions add another 1.07%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.9% 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 2,540 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 same number turns up on one other city pair in the data, including SEA to MCI (24), but none flew often enough under AS 484 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OGG to SAN only.
One caution: this is a thin sample. 281 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking AS 484
