Why B61347 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies B61347 comes in late, and what that does to the departure.
B61347 is usually the aircraft’s first flight of the day: the schedule gives it a median of 10.5 hours on the ground at DCA, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, B61347 pushed back an average of 13 minutes late; when it came in on time or early, an average of 11 minutes late.
Each departure is matched to the flight the same aircraft flew into DCA just before it, using the tail number in the DOT file, 1,063 of 1,111 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 |
|---|---|---|---|
| B61347 | 33% | 19% | 18% |
| 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 B61347’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B61347 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves DCA late, does that still matter by the time it reaches SJU?
B61347 pushes back an average of 14.2 minutes late and reaches the gate at SJU an average of 8.5 minutes late. The 5.7 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 20.6 minutes on the taxiways at DCA, 5.7 minutes shorter than a typical DCA departure in the same hour.
On arrival at SJU, B61347 spends 6.1 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 about what any arrival at SJU spends on the ground before reaching the gate.
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 SJU. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 41,923 departures from DCA scheduled in the clock hour B61347 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SJU (109,607 flights), not just B61347’s own. More on taxi time.

The hour it leaves DCA
Part of any flight’s record belongs to the clock rather than to the flight. B61347 has one departure time, so this is what that time is worth.
On-time arrival rate. 41,923 departures from DCA are scheduled in the 8 AM–9 AM hour over the period, against 435,076 across the whole day.
B61347 is scheduled out of DCA at 8:00 AM, in the 8 AM–9 AM bank. Departures from DCA in that hour arrive on time 83.2% of the time against 76.5% across the airport’s whole day — the slot alone is worth 6.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from DCA 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 B61347 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 10.2 percentage points.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
55 min late
against a median of 8 min early
B61347 has an average that understates its risk: a typical arrival is 8 min early, but the worst tenth are 63 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 1,126 records of B61347 operating DCA → SJU, 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.
