17 of 60 late departures made up the time and arrived on time, 28% of them. In the other direction, 19 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 KOA.
The worst days

The latest arrival of the period was on 15 August 2026, 30 hours 17 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 August 2026 | 30 hours 17 minutes | Late-arriving aircraft |
| 31 October 2025 | 8 hours 22 minutes | Late-arriving aircraft |
| 16 August 2026 | 7 hours 3 minutes | Late-arriving aircraft |

Delay causes
Why AA 663 runs late
Late-arriving aircraft accounts for 56% of the 6,891 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 24%Carrier
- 12%National Airspace System
- 7%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,891 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 6,891 delay minutes reported on AA 663.
Cancellations are rare at 0.27%, 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 routes
What a delay on this flight costs
8.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
At 2,860 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.
Every one of the 365 flights under AA 663 in the data flew PHX to KOA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 AA 663
For a booking, read AA 663 as 83.0% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
