Historical statistics for July 2025 to June 2026, not live status. For today’s AA 15, check with American Airlines.

AA 15 sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 350 flights, with a median arrival 7 minutes early.

These figures cover 350 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% 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 15 flies

AA 15 flies JFK to SFO without a single fixed slot. Its most common scheduled departure was 17:00, used on 232 of 350 flights. 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 17:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 15 runs 6 points better at 74.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

AA 15 next to JFK to SFO

Every carrier on JFK to SFO combined arrived on time 74.1% of the time across 6,730 flights, so AA 15 is about level with it. American flew 1,448 flights on the same city pair under all its flight numbers, including this one, and those ran 77.2% on time. Across its whole network American Airlines managed 74.4%, close to this flight's figure.

Across the year

AA 15 quarter by quarter

AA 15 did not run the same all year. Its best quarter was Jan–Mar 2026 at 82.5% on time and its weakest Apr–Jun 2026 at 66.7%, a swing of 16 points on roughly 88 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 15 did best on Tuesday at 87.8% on time and worst on Sunday at 62.5%. Each day rests on about 50 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 15 runs late

One category carries most of the weight here. National Airspace System accounts for 43% of the 6,880 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.

  • Late-arriving aircraft
    33%
  • Carrier
    22%
  • Extreme weather
    2%

43% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,977 minutes out of 6,880, against a national NAS share of 21%. The split is drawn from 6,880 delay minutes reported on AA 15.

Cancellations run at 3.14%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 10.4% 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 2,586 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 350 flights under AA 15 in the data flew JFK to SFO. 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. 350 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 15

For a booking, the cancellation rate is the figure to plan around on AA 15: 3.14% of its 350 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
