Share of 317 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 112 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 23 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 DCA.
The worst days
Worst days for AA 2648
The latest arrival of the period was on 27 March 2026, 4 hours 54 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, August, April and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 March 2026 | 4 hours 54 minutes | Carrier |
| 22 August 2026 | 4 hours | National Airspace System |
| 9 April 2026 | 3 hours 41 minutes | Late-arriving aircraft |

Delay causes
Why AA 2648 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 8,475 reported delay minutes.
- 35%Late-arriving aircraft
- 31%National Airspace System
- 27%Carrier
- 8%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,475 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 8,475 delay minutes reported on AA 2648.
Cancellations run at 3.35%, against 1.89% nationally. That is about one flight in 30 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
16.1% 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 919 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 two other city pairs in the data, including DFW to BNA (28) and BNA to DFW (27), but none flew often enough under AA 2648 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MIA to DCA only.
One caution: this is a thin sample. 328 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 2648
For a booking, the cancellation rate is the figure to plan around on AA 2648: 3.35% of its 328 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.
