Why F93442 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

Does a late aircraft delay this flight?
How often the plane that flies F93442 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F93442 pushed back an average of 77 minutes late; when it came in on time or early, an average of 6 minutes late.
Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 587 of 646 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 |
|---|---|---|---|
| F93442 | 41% | 82% | 21% |
| Network, same turn | 17% | 68% | 9% |
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 60 to 89 minutes. How often F93442’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F93442 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves ATL late, does that still matter by the time it reaches MIA?
F93442 pushes back an average of 42.3 minutes late and reaches the gate at MIA an average of 34.2 minutes late. The 8.1 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 19.1 minutes on the taxiways at ATL, 2.6 minutes longer than a typical ATL departure in the same hour.
On arrival at MIA, F93442 spends 10.0 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 MIA 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 MIA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 72,288 departures from ATL scheduled in the clock hour F93442 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MIA (340,467 flights), not just F93442’s own. More on taxi time.

The hour it leaves ATL
Part of any flight’s record belongs to the clock rather than to the flight. F93442 has one departure time, so this is what that time is worth.
On-time arrival rate. 72,288 departures from ATL are scheduled in the 10 PM–11 PM hour over the period, against 1,012,247 across the whole day.
F93442 is scheduled out of ATL at 10:50 PM, in the 10 PM–11 PM bank. Departures from ATL in that hour arrive on time 75.3% of the time against 78.7% across the airport’s whole day — the slot alone is worth 3.4 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from ATL 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.

Other routes F93442 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| BWI→ATL Baltimore to Atlanta | June 8–29, 2024 | 4 | — |
Because the same number has served different journeys, the statistics above describe only the route F93442 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.
114 min late
against a median of 9 min late
F93442 has an average that understates its risk: a typical arrival is 9 min late, but the worst tenth are 106 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. F93442 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 658 records of F93442 operating ATL → 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 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.
