Why B62230 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 B62230 on MKE → BOS. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B62230 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B62230 pushed back an average of 75 minutes late; when it came in on time or early, an average of 1 minute late.
Each departure is matched to the flight the same aircraft flew into MKE just before it, using the tail number in the DOT file, 646 of 652 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 |
|---|---|---|---|
| B62230 | 22% | 73% | 13% |
| 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 B62230’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B62230 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves MKE late, does that still matter by the time it reaches BOS?
On arrival at BOS, B62230 spends 8.7 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 BOS 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 BOS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 3,543 departures from MKE scheduled in the clock hour B62230 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BOS (440,886 flights), not just B62230’s own. More on taxi time.

The hour it leaves MKE
Part of any flight’s record belongs to the clock rather than to the flight. B62230 has one departure time, so this is what that time is worth.
On-time arrival rate. 3,543 departures from MKE are scheduled in the 9 AM–10 AM hour over the period, against 87,869 across the whole day.
B62230 is scheduled out of MKE at 9:55 AM, in the 9 AM–10 AM bank. Departures from MKE in that hour arrive on time 85.7% of the time against 80.7% across the airport’s whole day — the slot alone is worth 4.9 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MKE 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.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
81 min late
against a median of 9 min early
B62230 has an average that understates its risk: a typical arrival is 9 min early, but the worst tenth are 90 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 655 records of B62230 operating MKE → BOS, 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.
