AA 31 lands a B+, 5 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 365 flights, with a median arrival 8 minutes early.

These figures cover 365 flights between September 2025 and August 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 31 flies

AA 31 flies LAX to HNL without a single fixed slot. Its most common scheduled departure was 08:04, used on 54 of 365 flights, with 10:49 (44 flights) and 08:20 (42 flights) next.

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

A 08:04 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AA 31 runs 2 points worse at 81.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 31 quarter by quarter

AA 31 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Apr–Jun 2026 at 69.2%, a swing of 18 points on roughly 73 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.

Scale runs 60% to 90%.

By weekday, AA 31 ranged from 73.1% on Sunday to 84.9% on Monday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Arrival by arrival

How late AA 31 runs when it is late

AA 31 often beats the schedule: 140 of 365 completed flights, 38%, arrived 15 minutes or more early. The 66 late arrivals split 28 under half an hour, 19 between 30 and 60 minutes, and 19 an hour or more.

Share of 365 completed flights by arrival against schedule.

7 of 47 late departures made up the time and arrived on time, 15% of them. In the other direction, 26 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 HNL.

Delay causes

Why AA 31 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 3,755 reported delay minutes.

Carrier
36%
Late-arriving aircraft
28%
National Airspace System
22%
Extreme weather
14%

Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 3,755 delay minutes reported on AA 31.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

5.2% 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 about an hour, which a normal layover absorbs.

At 2,556 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 31 in the data flew LAX to HNL. 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 31

For a booking, read AA 31 as 81.9% on time with 0.00% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
