AA 824 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.3%. When something does go wrong the average delay runs a little over an hour. That rests on 361 flights, with a median arrival 9 minutes early.
Set against the rest of the country, AA 824's record is 8 points better than the US average of 77.3%. That gap is worth roughly 78 fewer late arrivals for every thousand flights.

These figures cover 361 flights between September 2025 and August 2026. The median arrival is 9 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.

A 08:55 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AA 824 runs level with that at 85.1%. 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 824 quarter by quarter
AA 824 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 21 points on roughly 72 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.

Share of 356 completed flights by arrival against schedule.
8 of 36 late departures made up the time and arrived on time, 22% of them. In the other direction, 25 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 LAX.

The latest arrival of the period was on 19 June 2026, 10 hours 11 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.

|---|---|---|
| 19 June 2026 | 10 hours 11 minutes | Late-arriving aircraft |
| 2 March 2026 | 6 hours 43 minutes | Late-arriving aircraft |

Delay causes
Why AA 824 runs late
Late-arriving aircraft accounts for 52% of the 3,816 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 22%Carrier
- 21%National Airspace System
- 5%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,816 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 3,816 delay minutes reported on AA 824.
Cancellations sit at 1.11% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.7% 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 2,402 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 361 flights under AA 824 in the data flew PHL to LAX. 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. 361 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 824
For a booking, AA 824 has one of the better records a US domestic flight can show: 85.1% on time and 1.11% cancelled. That is a base rate, not a promise about any single day.
