Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2648, check with American Airlines.
AA 2648 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 333 flights, with a median arrival 3 minutes late.
The national on-time rate over the same period is 77.6%, so AA 2648 runs 16 points behind the country as a whole. Across a thousand flights that is about 157 extra late arrivals.

These figures cover 333 flights between July 2025 and June 2026. Beyond the headline rate, 14.9% 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 2648 flies
AA 2648 flies MIA to DCA without a single fixed slot. Its most common scheduled departure was 19:17, used on 41 of 333 flights, with 18:29 (38 flights) and 17:51 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 19:1741 flights12.3%
- Departs 18:2938 flights11.4%
- Departs 17:5137 flights11.1%
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 19:17 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 2648 runs 6 points worse at 61.9%. 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 2648 next to MIA to DCA

Across the year
AA 2648 quarter by quarter
Quarter by quarter AA 2648 held fairly steady: 59.6% in Jul–Sep 2025, 64.4% in Oct–Dec 2025, 65.9% in Jan–Mar 2026 and 58.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights59.6%
- Oct–Dec 202560 flights64.4%
- Jan–Mar 202690 flights65.9%
- Apr–Jun 202691 flights58.9%
Scale runs 50% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, AA 2648 did best on Tuesday at 69.6% on time and worst on Sunday at 56.8%. Each day rests on about 48 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
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 8,543 reported delay minutes.
- 34%Late-arriving aircraft
- 32%Carrier
- 27%National Airspace System
- 7%Extreme weather
34% 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 8,543 reported delay minutes here, that single category outweighs weather by 5 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 8,543 delay minutes reported on AA 2648.
Cancellations run at 3.00%, against 1.81% nationally. That is roughly 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.9% 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 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. 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 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. 333 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: 3.00% of its 333 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.
