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 2026 at 49.1%, a swing of 32 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 89.1% on time and worst on Friday at 58.8%. Each day rests on about 51 flights, so a gap of 30 points is worth noticing but could still narrow in another year.
Arrival by arrival

Share of 344 completed flights by arrival against schedule.
31 of 113 late departures made up the time and arrived on time, 27% of them. In the other direction, 19 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 FLL.
The worst days
Worst days for AA 1864
The latest arrival of the period was on 7 August 2026, 4 hours 44 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 4 hours 44 minutes | Carrier |

Delay causes
Why AA 1864 runs late
Late-arriving aircraft accounts for 54% of the 7,140 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 28%Carrier
- 17%National Airspace System
- 1%Extreme weather
- 0%Security
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,140 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 7,140 delay minutes reported on AA 1864.
Cancellations run at 3.91%, against 1.89% nationally. That is about 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
14.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
Every one of the 358 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. 358 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: 3.91% of its 358 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.
