Across the year
AA 1389 quarter by quarter
AA 1389 did not run the same all year. Its best quarter was Oct–Dec 2025 at 64.6% on time and its weakest Jul–Sep 2026 at 46.0%, a swing of 19 points on roughly 76 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.

- Jan–Mar 202690 flights48.8%
- Apr–Jun 202641 flights57.9%

Scale runs 40% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, AA 1389 did best on Tuesday at 68.9% on time and worst on Sunday at 50.0%. Each day rests on about 43 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

23 of 119 late departures made up the time and arrived on time, 19% of them. In the other direction, 22 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 LGA.

The latest arrival of the period was on 24 October 2025, 9 hours 17 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across October, July, November and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 October 2025 | 9 hours 17 minutes | Extreme weather |
| 4 July 2026 | 3 hours 43 minutes | National Airspace System |

Delay causes
Why AA 1389 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 7,395 reported delay minutes.
- 32%Late-arriving aircraft
- 30%Carrier
- 28%National Airspace System
- 11%Extreme weather
No single cause dominates. late-arriving aircraft at 32%, carrier at 30% and national airspace system at 28% split the 7,395 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 7,395 delay minutes reported on AA 1389.
Cancellations run at 6.95%, against 1.89% nationally. That is about one flight in fifteen 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
15.6% 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 1,096 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.
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. 302 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: 6.95% of its 302 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
