AA 1357 earns a D, which is as low as this site's scale goes for a reason. Only 57.5% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.3%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 326 flights, with a median arrival 8 minutes late.

The national on-time rate over the same period is 77.3%, so AA 1357 runs 20 points behind the country as a whole. Across a thousand flights that is about 198 extra late arrivals.

Across the year

AA 1357 quarter by quarter

AA 1357 did not run the same all year. Its best quarter was Oct–Dec 2025 at 60.9% on time and its weakest Jul–Sep 2026 at 45.6%, a swing of 15 points on roughly 82 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.

Scale runs 35% to 65%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1357 did best on Monday at 65.2% on time and worst on Saturday at 47.5%. Each day rests on about 47 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Share of 315 completed flights by arrival against schedule.

16 of 129 late departures made up the time and arrived on time, 12% of them. In the other direction, 21 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 JFK.

The worst days

The latest arrival of the period was on 26 December 2025, 10 hours 33 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across December, January, July, August and October, with no single month standing out.

Delay causes

Why AA 1357 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 9,912 reported delay minutes.

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.6 times the usual weather exposure. The split is drawn from 9,912 delay minutes reported on AA 1357.

Cancellations run at 2.76%, against 1.89% nationally. That is roughly one flight in 40 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

18.1% 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 1,089 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.

The same number turns up on three other city pairs in the data, including ORD to RSW (30), MIA to BDL (1) and ORD to PHL (1), but none flew often enough under AA 1357 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MIA to JFK only.

One caution: this is a thin sample. 326 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 1357

For a booking, the cancellation rate is the figure to plan around on AA 1357: 2.76% of its 326 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.
