Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA2139 | 64.6% | 3.68% | -2 min | 21.0% | 625 |
| American Airlines on DCA → MCO | 79.1% | 2.04% | -9 min | 9.0% | 5,995 |
| All DCA → MCO flights | 77.0% | 1.99% | -7 min | 10.1% | 15,032 |
AA2139 has cancelled 3.68% of its scheduled departures (23 of 625), against 1.99% for all DCA → MCO flights — this specific departure cancels 1.7 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 AA2139 specifically, not about the route it flies.
21.0% of AA2139’s arrivals were an hour or more late, against 10.1% across DCA → MCO, so the long delays are more common on this number than on the route.

Why AA2139 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies AA2139 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA2139 pushed back an average of 54 minutes late; when it came in on time or early, an average of 1 minute late.
Matched by tail number to the aircraft’s previous flight into DCA: 551 of 603 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
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 |
|---|---|---|---|
| AA2139 | 31% | 58% | 11% |
| Network, same turn | 17% | 69% | 9% |
62 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AA2139’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA2139 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves DCA late, does that still matter by the time it reaches MCO?
AA2139 pushes back an average of 31.3 minutes late and reaches the gate at MCO an average of 28.9 minutes late. The 2.4 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. Its 23.6 minutes on the taxiways at DCA is about what any departure from the airport in that hour spends.
On arrival at MCO, AA2139 spends 14.2 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 3.3 minutes longer than a typical MCO arrival (10.9 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 38,015 DCA departures. Taxi-in is landing to gate, set against 510,310 arrivals at MCO. More on taxi time.

The hour it leaves DCA
AA2139 has one departure time, 5:30 PM, so this is what that hour at DCA is worth.
On-time arrival rate. 38,015 departures from DCA are scheduled in the 5 PM–6 PM hour over the period, against 447,230 across the whole day.
AA2139 is scheduled out of DCA at 5:30 PM, in the 5 PM–6 PM bank. Departures from DCA in that hour arrive on time 66.2% of the time against 76.3% across the airport’s whole day — the slot alone is worth 10.1 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from DCA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
132 min late
against a median of 2 min early
AA2139 has an average that understates its risk: a typical arrival is 2 min early, but the worst tenth are 134 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 625 records of AA2139 operating DCA → MCO, 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 reported separately, not in the on-time rate.
