Why F91555 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies F91555 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91555 pushed back an average of 100 minutes late; when it came in on time or early, an average of 3 minutes late.
Matched by tail number to the aircraft’s previous flight into CLT: 569 of 587 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| F91555 | 24% | 86% | 11% |
| Network, same turn | 18% | 85% | 10% |
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 F91555’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F91555 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves CLT late, does that still matter by the time it reaches MCO?
F91555 pushes back an average of 28.3 minutes late and reaches the gate at MCO an average of 24.0 minutes late. The 4.4 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. It spends 23.7 minutes on the taxiways at CLT, 7.2 minutes longer than a typical CLT departure in the same hour.
On arrival at MCO, F91555 spends 14.2 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 3.3 minutes longer than a typical MCO arrival (10.9 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 3,319 CLT departures. Taxi-in is landing to gate, set against 510,310 arrivals at MCO. More on taxi time.

The hour it leaves CLT
F91555 has one departure time, 5:45 AM, so this is what that hour at CLT is worth.
On-time arrival rate. 3,319 departures from CLT are scheduled in the 5 AM–6 AM hour over the period, against 633,368 across the whole day.

Both airport figures cover every destination from CLT, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

78 min late
against a median of 3 min early
