Historical statistics for July 2025 to June 2026, not live status. For today’s AA 663, check with American Airlines.

AA 663 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 8 minutes early.

Set against the rest of the country, AA 663's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 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.

Schedule

When AA 663 flies

AA 663 flies PHX to KOA without a single fixed slot. Its most common scheduled departure was 11:03, used on 59 of 365 flights, with 10:58 (44 flights) and 10:30 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 11:03 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AA 663 runs 5 points better at 83.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AA 663 quarter by quarter

Quarter by quarter AA 663 held fairly steady: 87.0% in Jul–Sep 2025, 81.5% in Oct–Dec 2025, 83.1% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights87.0%
Oct–Dec 202592 flights81.5%
Jan–Mar 202690 flights83.1%
Apr–Jun 202691 flights83.5%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, AA 663 ranged from 78.8% on Wednesday to 90.2% on Saturday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AA 663 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 4,688 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
32%

Extreme weather
1%

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,688 reported delay minutes here, that single category outweighs weather by 41 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,688 delay minutes reported on AA 663.

Cancellations are rare at 0.27%, below the national 1.81% 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

7.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, 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 83.8% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
