What stands out
How AA2648 compares to other flight numbers, not just to itself.
Which day you fly matters unusually much here, a wider weekday spread than 98% of 1,710 comparable flight numbers.
70.6% on time on a typical Saturday, against 47.8% on a Thursday.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA2648 | 59.3% | 3.13% | 6 min | 13.7% | 989 |
| American Airlines on MIA → DCA | 73.8% | 2.10% | -5 min | 9.2% | 10,822 |
| All MIA → DCA flights | 74.5% | 1.97% | -5 min | 9.0% | 11,974 |
AA2648 has cancelled 3.13% of its scheduled departures (31 of 989), against 1.97% for all MIA → DCA flights — this specific departure cancels 1.2 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about AA2648 specifically, not about the route it flies.

Why AA2648 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for AA2648 on MIA → DCA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA2648 comes in late, and what that does to the departure.
AA2648 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.4 hours on the ground at MIA, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA2648 pushed back an average of 33 minutes late; when it came in on time or early, an average of 19 minutes late.
Each departure is matched to the flight the same aircraft flew into MIA just before it, using the tail number in the DOT file, 675 of 961 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| AA2648 | 20% | 56% | 31% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often AA2648’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often AA2648 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MIA late, does that still matter by the time it reaches DCA?
On arrival at DCA, AA2648 spends 6.6 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.0 minutes shorter than a typical DCA arrival (7.6 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached DCA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 30,212 departures from MIA scheduled in the clock hour AA2648 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DCA (435,126 flights), not just AA2648’s own. More on taxi time.

The hour it leaves MIA
Part of any flight’s record belongs to the clock rather than to the flight. AA2648 has one departure time, so this is what that time is worth.
On-time arrival rate. 30,212 departures from MIA are scheduled in the 7 PM–8 PM hour over the period, against 340,469 across the whole day.
AA2648 is scheduled out of MIA at 7:25 PM, in the 7 PM–8 PM bank. Departures from MIA in that hour arrive on time 64.4% of the time against 73.2% across the airport’s whole day — the slot alone is worth 8.8 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from MIA to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does AA2648 run worse on particular days?
Saturday is historically the most reliable day and Thursday the least, a gap of 22.8 percentage points.

Other routes AA2648 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

Because the same number has served different journeys, the statistics above describe only the route AA2648 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
75 min late
against a median of 6 min late
AA2648 has an average that understates its risk: a typical arrival is 6 min late, but the worst tenth are 69 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|

| AA2648 this flight | American Airlines | 59.3% | 6 min late | 989 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA2648 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 989 records of AA2648 operating MIA → DCA, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
