Why F91544 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
Share of the delay minutes US DOT attributed to each cause for F91544 on CLE → RSW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F91544 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91544 pushed back an average of 18 minutes late; when it came in on time or early, an average of 1 minute early.
Each departure is matched to the flight the same aircraft flew into CLE just before it, using the tail number in the DOT file, 537 of 629 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 |
|---|---|---|---|
| F91544 | 30% | 31% | 9% |
| Network, same turn | 33% | 24% | 11% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 3 to 6 hours. How often F91544’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often F91544 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves CLE late, does that still matter by the time it reaches RSW?
F91544 pushes back an average of 8.5 minutes late and reaches the gate at RSW an average of 3.9 minutes late. The 4.7 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 18.4 minutes on the taxiways at CLE, 2.7 minutes longer than a typical CLE departure in the same hour.
On arrival at RSW, F91544 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 2.9 minutes longer than a typical RSW arrival (5.6 min).
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 RSW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 4,993 departures from CLE scheduled in the clock hour F91544 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at RSW (107,489 flights), not just F91544’s own. More on taxi time.

The hour it leaves CLE
Part of any flight’s record belongs to the clock rather than to the flight. F91544 has one departure time, so this is what that time is worth.
On-time arrival rate. 4,993 departures from CLE are scheduled in the 5 AM–6 AM hour over the period, against 126,883 across the whole day.
F91544 is scheduled out of CLE at 5:30 AM, in the 5 AM–6 AM bank. Departures from CLE in that hour arrive on time 89.4% of the time against 80.9% across the airport’s whole day — the slot alone is worth 8.5 points better before anything about this particular flight is considered.
The two airport figures cover every departure from CLE 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 F91544 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 |
|---|---|---|---|
| MCO→ORD Orlando to Chicago | August 16–30, 2023 | 3 | — |
Because the same number has served different journeys, the statistics above describe only the route F91544 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 639 records of F91544 operating CLE → RSW, 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.
