Why YX5660 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
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies YX5660 comes in late, and what that does to the departure.
YX5660 is usually the aircraft’s first flight of the day: the schedule gives it a median of 10.9 hours on the ground at IND, so its “inbound” is mostly the aircraft’s arrival the evening before.
The aircraft flying YX5660 came in 15 or more minutes late on 23% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into IND just before it, using the tail number in the DOT file, 312 of 599 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 |
|---|---|
| YX5660 | 23% |
| Network, same turn | 29% |
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 YX5660’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves IND late, does that still matter by the time it reaches LGA?
YX5660 pushes back an average of 3.5 minutes late and reaches the gate at LGA an average of 2.7 minutes early. The 6.2 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 17.6 minutes on the taxiways at IND, 1.4 minutes longer than a typical IND departure in the same hour.
On arrival at LGA, YX5660 spends 8.3 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 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 8,438 departures from IND scheduled in the clock hour YX5660 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 YX5660’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. YX5660 has one departure time, so this is what that time is worth.
On-time arrival rate. 8,438 departures from IND are scheduled in the 8 AM–9 AM hour over the period, against 147,128 across the whole day.
YX5660 is scheduled out of IND at 8:00 AM, in the 8 AM–9 AM bank. Departures from IND in that hour arrive on time 87.8% of the time against 81.9% across the airport’s whole day — the slot alone is worth 6.0 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 YX5660 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX5660 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 614 records of YX5660 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.
