Why YX5616 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
Share of the delay minutes US DOT attributed to each cause for YX5616 on BOS → IND. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX5616 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX5616 pushed back an average of 49 minutes late; when it came in on time or early, an average of 3 minutes early.
Each departure is matched to the flight the same aircraft flew into BOS just before it, using the tail number in the DOT file, 649 of 670 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 |
|---|---|---|---|
| YX5616 | 32% | 66% | 6% |
| Network, same turn | 18% | 85% | 10% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often YX5616’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often YX5616 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves BOS late, does that still matter by the time it reaches IND?
YX5616 pushes back an average of 15.0 minutes late and reaches the gate at IND an average of 4.4 minutes late. The 10.6 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 25.9 minutes on the taxiways at BOS, 2.4 minutes longer than a typical BOS departure in the same hour.
On arrival at IND, YX5616 spends 7.9 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 IND 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 IND. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 27,363 departures from BOS scheduled in the clock hour YX5616 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IND (147,137 flights), not just YX5616’s own. More on taxi time.

The hour it leaves BOS
Part of any flight’s record belongs to the clock rather than to the flight. YX5616 has one departure time, so this is what that time is worth.
On-time arrival rate. 27,363 departures from BOS are scheduled in the 6 PM–7 PM hour over the period, against 440,893 across the whole day.
YX5616 is scheduled out of BOS at 6:25 PM, in the 6 PM–7 PM bank. Departures from BOS in that hour arrive on time 66.3% of the time against 77.2% across the airport’s whole day — the slot alone is worth 10.9 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from BOS 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.

Because the same number has served different journeys, the statistics above describe only the route YX5616 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.
62 min late
against a median of 11 min early
YX5616 has an average that understates its risk: a typical arrival is 11 min early, but the worst tenth are 73 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX5616 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 687 records of YX5616 operating BOS → IND, 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.
