Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1357, check with American Airlines.

AA 1357 earns a D, which is as low as this site's scale goes for a reason. Only 56.2% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. 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 9 minutes late.

The national on-time rate over the same period is 77.6%, so AA 1357 runs 21 points behind the country as a whole. Across a thousand flights that is about 214 extra late arrivals.

These figures cover 326 flights between July 2025 and June 2026. Beyond the headline rate, 18.6% 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 1357 flies

AA 1357 flies MIA to JFK without a single fixed slot. Its most common scheduled departure was 19:20, used on 63 of 326 flights, with 19:45 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 1357 runs 12 points worse at 56.2%. 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 1357 next to MIA to JFK

Every carrier on MIA to JFK combined arrived on time 71.9% of the time across 4,555 flights, so AA 1357 is 16 points behind it. American flew 2,660 flights on the same city pair under all its flight numbers, including this one, and those ran 70.9% on time. Across its whole network American Airlines managed 74.4%, which this flight trails by 18 points.

Across the year

AA 1357 quarter by quarter

Quarter by quarter AA 1357 held fairly steady: 51.1% in Jul–Sep 2025, 60.9% in Oct–Dec 2025, 53.4% in Jan–Mar 2026 and 58.3% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights51.1%
Oct–Dec 202588 flights60.9%
Jan–Mar 202662 flights53.4%
Apr–Jun 202684 flights58.3%

Scale runs 45% to 65%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1357 did best on Monday at 72.7% on time and worst on Sunday at 41.9%. Each day rests on about 47 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

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 11,000 reported delay minutes.

Late-arriving aircraft
35%
National Airspace System
26%
Carrier
23%
Extreme weather
15%
Security
1%

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 2.4 times the usual weather exposure. The split is drawn from 10,555 delay minutes reported on AA 1357.

Cancellations sit at 2.45% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

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. 18.6% 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 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. 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.

The same number turns up on three other city pairs in the data, including ORD to RSW (30), ORD to PHL (1) and MIA to BDL (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, AA 1357 is a flight to put a long connection behind. 18.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
