Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1389, check with American Airlines.
AA 1389 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 301 flights, with a median arrival 8 minutes late.
The national on-time rate over the same period is 77.6%, so AA 1389 runs 16 points behind the country as a whole. Across a thousand flights that is about 158 extra late arrivals.

These figures cover 301 flights between July 2025 and June 2026. Beyond the headline rate, 14.6% 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 1389 flies
AA 1389 flies MIA to LGA without a single fixed slot. Its most common scheduled departure was 20:50, used on 81 of 301 flights, with 20:35 (59 flights) and 20:55 (54 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 20:50 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AA 1389 runs 9 points worse at 61.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AA 1389 quarter by quarter
AA 1389 did not run the same all year. Its best quarter was Jul–Sep 2025 at 74.1% on time and its weakest Jan–Mar 2026 at 48.8%, a swing of 25 points on roughly 75 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.
- Jul–Sep 202587 flights74.1%
- Oct–Dec 202583 flights64.6%
- Jan–Mar 202690 flights48.8%
- Apr–Jun 202641 flights57.9%
Scale runs 40% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, AA 1389 did best on Tuesday at 71.1% on time and worst on Sunday at 55.0%. Each day rests on about 43 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1389 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 8,491 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.
- 47%Late-arriving aircraft
- 28%Carrier
- 17%National Airspace System
- 7%Extreme weather
47% 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 8,491 reported delay minutes here, that single category outweighs weather by 6 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 8,491 delay minutes reported on AA 1389.
Cancellations run at 4.98%, against 1.81% nationally. That is about one flight in twenty 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. 14.6% 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 1,096 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 one other city pair in the data, including ORD to CLT (44), but none flew often enough under AA 1389 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MIA to LGA only.
One caution: this is a thin sample. 301 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 1389
For a booking, the cancellation rate is the figure to plan around on AA 1389: 4.98% of its 301 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.
