Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1864, check with American Airlines.
AA 1864 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 10 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 361 flights, with a median arrival 2 minutes early.
The national on-time rate over the same period is 77.6%, so AA 1864 runs 10 points behind the country as a whole. Across a thousand flights that is about 95 extra late arrivals.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 13.6% 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 1864 flies
AA 1864 flies PHL to FLL without a single fixed slot. Its most common scheduled departure was 19:00, used on 87 of 361 flights, with 18:20 (37 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 19:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 1864 runs level with that at 68.1%. 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 1864 next to PHL to FLL

Across the year
AA 1864 quarter by quarter
AA 1864 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.1% on time and its weakest Jul–Sep 2025 at 47.1%, a swing of 34 points on roughly 90 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 1864 did best on Tuesday at 80.4% on time and worst on Friday at 58.8%. Each day rests on about 52 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1864 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 7,772 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.

- 24%Carrier
- 16%National Airspace System
- 3%Extreme weather
- 0%Security
57% 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 7,772 reported delay minutes here, that single category outweighs weather by 20 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 7,772 delay minutes reported on AA 1864.
Cancellations run at 4.43%, against 1.81% nationally. That is roughly one flight in 25 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. 13.6% 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.
The 993 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 361 flights under AA 1864 in the data flew PHL to FLL. 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 1864
For a booking, the cancellation rate is the figure to plan around on AA 1864: 4.43% of its 361 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.
