Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| F92173 | 69.3% | 2.92% | -3 min | 12.2% | 651 |
| Frontier Airlines on FLL → ATL | 61.4% | 3.48% | 4 min | 17.6% | 1,953 |
| All FLL → ATL flights | 71.4% | 1.57% | -3 min | 11.2% | 22,812 |
F92173 has cancelled 2.92% of its scheduled departures (19 of 651), against 1.57% for all FLL → ATL flights — this specific departure cancels 1.4 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about F92173 specifically, not about the route it flies.

Why F92173 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 F92173 on FLL → ATL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F92173 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F92173 pushed back an average of 46 minutes late; when it came in on time or early, an average of 4 minutes late.
Each departure is matched to the flight the same aircraft flew into FLL just before it, using the tail number in the DOT file, 593 of 632 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 |
|---|---|---|---|
| F92173 | 32% | 45% | 12% |
| 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 F92173’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often F92173 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves FLL late, does that still matter by the time it reaches ATL?
On arrival at ATL, F92173 spends 21.8 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 12.2 minutes longer than a typical ATL arrival (9.6 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 ATL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 21,980 departures from FLL scheduled in the clock hour F92173 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ATL (1,012,161 flights), not just F92173’s own. More on taxi time.

The hour it leaves FLL
Part of any flight’s record belongs to the clock rather than to the flight. F92173 has one departure time, so this is what that time is worth.
On-time arrival rate. 21,980 departures from FLL are scheduled in the 6 AM–7 AM hour over the period, against 278,691 across the whole day.
F92173 is scheduled out of FLL at 6:00 AM, in the 6 AM–7 AM bank. Departures from FLL in that hour arrive on time 91.3% of the time against 72.6% across the airport’s whole day — the slot alone is worth 18.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from FLL 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 F92173 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 |
|---|---|---|---|
| LAS→PDX Las Vegas to Portland | July 2, 2023 – November 15, 2023 | 68 | — |
Because the same number has served different journeys, the statistics above describe only the route F92173 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.
78 min late
against a median of 3 min early
F92173 has an average that understates its risk: a typical arrival is 3 min early, but the worst tenth are 81 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. F92173 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 651 records of F92173 operating FLL → ATL, 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.
