Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2391, check with American Airlines.
AA 2391 sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 286 flights, with a median arrival 5 minutes early.
The national on-time rate over the same period is 77.6%, so AA 2391 runs 4 points behind the country as a whole. Across a thousand flights that is about 40 extra late arrivals.

These figures cover 286 flights between July 2025 and June 2026. Beyond the headline rate, 9.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When AA 2391 flies
AA 2391 flies PHX to ATL without a single fixed slot. Its most common scheduled departure was 15:45, used on 50 of 286 flights, with 16:10 (35 flights) and 16:39 (31 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 15:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AA 2391 runs level with that at 73.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AA 2391 quarter by quarter
AA 2391 did not run the same all year. Its best quarter was Jan–Mar 2026 at 82.7% on time and its weakest Oct–Dec 2025 at 69.6%, a swing of 13 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.

By weekday, AA 2391 ranged from 66.7% on Sunday to 77.6% on Monday. With about 41 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 2391 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 5,289 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.
- 60%Late-arriving aircraft
- 31%Carrier
- 8%National Airspace System
60% 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 5,289 reported delay minutes here, that single category outweighs weather by 60 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 5,289 delay minutes reported on AA 2391.
Cancellations are rare at 0.70%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 1,587 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 four other city pairs in the data, including PHL to ORD (6), ORD to PHL (4) and MEM to PHX (1), but none flew often enough under AA 2391 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHX to ATL only.
One caution: this is a thin sample. 286 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
