Why YX4793 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 YX4793 on LGA → IND. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX4793 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX4793 pushed back an average of 46 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into LGA just before it, using the tail number in the DOT file, 671 of 712 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 |
|---|---|---|---|
| YX4793 | 23% | 55% | 7% |
| 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 YX4793’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often YX4793 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves LGA late, does that still matter by the time it reaches IND?
YX4793 pushes back an average of 13.3 minutes late and reaches the gate at IND an average of 9.5 minutes late. The 3.7 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. Its 26.6 minutes on the taxiways at LGA is about what any departure from the airport in that hour spends.
On arrival at IND, YX4793 spends 9.6 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 2.6 minutes longer than a typical IND arrival (7.0 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 IND. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 29,634 departures from LGA scheduled in the clock hour YX4793 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IND (147,137 flights), not just YX4793’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. YX4793 has one departure time, so this is what that time is worth.
On-time arrival rate. 29,634 departures from LGA are scheduled in the 5 PM–6 PM hour over the period, against 456,467 across the whole day.
YX4793 is scheduled out of LGA at 5:40 PM, in the 5 PM–6 PM bank. Departures from LGA in that hour arrive on time 70.2% of the time against 78.3% across the airport’s whole day — the slot alone is worth 8.1 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.

Because the same number has served different journeys, the statistics above describe only the route YX4793 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.
66 min late
against a median of 8 min early
YX4793 has an average that understates its risk: a typical arrival is 8 min early, but the worst tenth are 74 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX4793 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 737 records of YX4793 operating LGA → IND, 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.
