Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| F93423 | 63.2% | 6.23% | -1 min | 16.0% | 754 |
| Frontier Airlines on LGA → DFW | 66.0% | 5.52% | -2 min | 15.1% | 1,014 |
| All LGA → DFW flights | 74.7% | 3.23% | -9 min | 10.9% | 20,144 |
F93423 has cancelled 6.23% of its scheduled departures (47 of 754), against 3.23% for all LGA → DFW flights — this specific departure cancels 3.0 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 F93423 specifically, not about the route it flies.

Why F93423 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
Share of the delay minutes US DOT attributed to each cause for F93423 on LGA → DFW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F93423 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F93423 pushed back an average of 85 minutes late; when it came in on time or early, an average of 2 minutes late.
Each departure is matched to the flight the same aircraft flew into LGA just before it, using the tail number in the DOT file, 697 of 707 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 |
|---|---|---|---|
| F93423 | 41% | 92% | 12% |
| 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 F93423’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F93423 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves LGA late, does that still matter by the time it reaches DFW?
F93423 pushes back an average of 45.4 minutes late and reaches the gate at DFW an average of 29.9 minutes late. The 15.5 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. Its 18.4 minutes on the taxiways at LGA is about what any departure from the airport in that hour spends.
On arrival at DFW, F93423 spends 14.3 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 DFW 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 DFW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 2,721 departures from LGA scheduled in the clock hour F93423 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DFW (961,642 flights), not just F93423’s own. More on taxi time.

The hour it leaves LGA
Part of any flight’s record belongs to the clock rather than to the flight. F93423 has one departure time, so this is what that time is worth.
On-time arrival rate. 2,721 departures from LGA are scheduled in the 10 PM–11 PM hour over the period, against 456,467 across the whole day.
F93423 is scheduled out of LGA at 10:00 PM, in the 10 PM–11 PM bank. Departures from LGA in that hour arrive on time 67.6% of the time against 78.3% across the airport’s whole day — the slot alone is worth 10.7 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from LGA 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.
89 min late
against a median of 1 min early
F93423 has an average that understates its risk: a typical arrival is 1 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.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. F93423 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 754 records of F93423 operating LGA → DFW, 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.
