Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX4626 | 82.1% | 1.44% | -5 min | 3.4% | 624 |
| Republic Airways on IND → DCA | 82.3% | 2.32% | -7 min | 5.1% | 5,305 |
| All IND → DCA flights | 80.8% | 2.84% | -7 min | 6.5% | 6,225 |
YX4626 has cancelled 1.44% of its scheduled departures (9 of 624), against 2.84% for all IND → DCA flights — this specific departure cancels 1.4 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 YX4626 specifically, not about the route it flies.

Why YX4626 runs late
Where US DOT attributed the delay minutes on this flight.
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
the inbound aircraft was late, so this flight started late
Share of the delay minutes US DOT attributed to each cause for YX4626 on IND → DCA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX4626 comes in late, and what that does to the departure.
YX4626 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.4 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, YX4626 pushed back an average of 0 minutes early; when it came in on time or early, an average of 0 minutes 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, 501 of 616 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 |
|---|---|---|---|
| YX4626 | 33% | 9% | 6% |
| 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 YX4626’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often YX4626 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves IND late, does that still matter by the time it reaches DCA?
On arrival at DCA, YX4626 spends 9.4 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 1.8 minutes longer than a typical DCA arrival (7.6 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 DCA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 16,451 departures from IND scheduled in the clock hour YX4626 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DCA (435,126 flights), not just YX4626’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. YX4626 has one departure time, so this is what that time is worth.
On-time arrival rate. 16,451 departures from IND are scheduled in the 6 AM–7 AM hour over the period, against 147,128 across the whole day.
YX4626 is scheduled out of IND at 6:00 AM, in the 6 AM–7 AM bank. Departures from IND in that hour arrive on time 90.9% of the time against 81.9% across the airport’s whole day — the slot alone is worth 9.0 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.

Other routes YX4626 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| BOS→DCA Boston to Washington | October 12, 2024 – November 2, 2024 | 5 | — |
| PHL→DCA Philadelphia to Washington | July 2, 2023 – April 3, 2024 | 253 | 94.4% |
Because the same number has served different journeys, the statistics above describe only the route YX4626 currently operates. Blending them would produce an average of two different flights.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. YX4626 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 624 records of YX4626 operating IND → DCA, 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.
