Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX4797 | 90.0% | 1.92% | -10 min | 2.3% | 677 |
| Republic Airways on IND → LGA | 84.7% | 3.29% | -9 min | 5.3% | 6,694 |
| All IND → LGA flights | 85.1% | 3.15% | -10 min | 5.3% | 7,980 |
YX4797 has cancelled 1.92% of its scheduled departures (13 of 677), against 3.15% for all IND → LGA flights — this specific departure cancels 1.2 percentage points less 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 YX4797 specifically, not about the route it flies.

Why YX4797 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
weather severe enough to stop this flight specifically
the inbound aircraft was late, so this flight started late
Share of the delay minutes US DOT attributed to each cause for YX4797 on IND → LGA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX4797 comes in late, and what that does to the departure.
YX4797 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.9 hours on the ground at IND, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, YX4797 pushed back an average of 2 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 IND just before it, using the tail number in the DOT file, 528 of 664 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 |
|---|---|---|---|
| YX4797 | 28% | 11% | 7% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often YX4797’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often YX4797 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves IND late, does that still matter by the time it reaches LGA?
YX4797 pushes back an average of 0.9 minutes late and reaches the gate at LGA an average of 4.4 minutes early. The 5.3 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 16.9 minutes on the taxiways at IND is about what any departure from the airport in that hour spends.
On arrival at LGA, YX4797 spends 9.1 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 LGA 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 LGA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 15,537 departures from IND scheduled in the clock hour YX4797 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LGA (456,481 flights), not just YX4797’s own. More on taxi time.

The hour it leaves IND
Part of any flight’s record belongs to the clock rather than to the flight. YX4797 has one departure time, so this is what that time is worth.
On-time arrival rate. 15,537 departures from IND are scheduled in the 7 AM–8 AM hour over the period, against 147,128 across the whole day.
YX4797 is scheduled out of IND at 7:00 AM, in the 7 AM–8 AM bank. Departures from IND in that hour arrive on time 88.3% of the time against 81.9% across the airport’s whole day — the slot alone is worth 6.4 points better before anything about this particular flight is considered.
The two airport figures cover every departure from IND 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 YX4797 currently operates. Blending them would produce an average of two different flights.

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. YX4797 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 677 records of YX4797 operating IND → LGA, 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.
