Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX5635 | 75.4% | 6.73% | -11 min | 10.8% | 624 |
| Republic Airways on LGA → IND | 80.0% | 4.12% | -12 min | 8.5% | 6,920 |
| All LGA → IND flights | 80.4% | 3.90% | -13 min | 8.3% | 8,203 |
YX5635 has cancelled 6.73% of its scheduled departures (42 of 624), against 3.90% for all LGA → IND flights — this specific departure cancels 2.8 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 YX5635 specifically, not about the route it flies.
10.8% of YX5635’s arrivals were an hour or more late, against 8.3% across LGA → IND, so the long delays are more common on this number than on the route.

Why YX5635 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

Does a late aircraft delay this flight?
How often the plane that flies YX5635 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX5635 pushed back an average of 51 minutes late; when it came in on time or early, an average of 2 minutes early.
Matched by tail number to the aircraft’s previous flight into LGA: 571 of 588 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
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 |
|---|---|---|---|
| YX5635 | 24% | 63% | 7% |
| Network, same turn | 18% | 85% | 10% |
55 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often YX5635’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often YX5635 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?
YX5635 pushes back an average of 14.5 minutes late and reaches the gate at IND an average of 5.5 minutes late. The 9.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 29.2 minutes on the taxiways at LGA, 2.2 minutes longer than a typical LGA departure in the same hour.
On arrival at IND, YX5635 spends 7.9 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 IND spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 30,384 LGA departures. Taxi-in is landing to gate, set against 151,052 arrivals at IND. More on taxi time.

The hour it leaves LGA
YX5635 has one departure time, 5:30 PM, so this is what that hour at LGA is worth.
On-time arrival rate. 30,384 departures from LGA are scheduled in the 5 PM–6 PM hour over the period, against 467,462 across the whole day.
YX5635 is scheduled out of LGA at 5:30 PM, in the 5 PM–6 PM bank. Departures from LGA in that hour arrive on time 69.9% of the time against 78.1% across the airport’s whole day — the slot alone is worth 8.1 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from LGA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
65 min late
against a median of 11 min early

Data and methodology
Calculated by FlyerIntel from 624 records of YX5635 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 reported separately, not in the on-time rate.
