Why AA2247 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
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies AA2247 comes in late, and what that does to the departure.
The aircraft flying AA2247 came in 15 or more minutes late on 11% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Matched by tail number to the aircraft’s previous flight into BOS: 710 of 730 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 |
|---|---|
| AA2247 | 11% |
| Network, same turn | 18% |
55 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 45 to 59 minutes. How often AA2247’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves BOS late, does that still matter by the time it reaches MIA?
AA2247 pushes back an average of 17.9 minutes late and reaches the gate at MIA an average of 9.8 minutes late. The 8.1 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 20.0 minutes on the taxiways at BOS is about what any departure from the airport in that hour spends.
On arrival at MIA, AA2247 spends 8.6 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 1.2 minutes shorter than a typical MIA arrival (9.7 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 20,695 BOS departures. Taxi-in is landing to gate, set against 349,140 arrivals at MIA. More on taxi time.

The hour it leaves BOS
AA2247 has one departure time, 1:05 PM, so this is what that hour at BOS is worth.
On-time arrival rate. 20,695 departures from BOS are scheduled in the 1 PM–2 PM hour over the period, against 454,081 across the whole day.
AA2247 is scheduled out of BOS at 1:05 PM, in the 1 PM–2 PM bank. Departures from BOS in that hour arrive on time 77.9% of the time against 77.0% across the airport’s whole day, so the hour AA2247 leaves in is an ordinary one for BOS and explains nothing about its record either way.
Both airport figures cover every destination from BOS, 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.
58 min late
against a median of 7 min early
AA2247 has an average that understates its risk: a typical arrival is 7 min early, but the worst tenth are 65 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 740 records of AA2247 operating BOS → MIA, 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.
