Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX3464 | 82.8% | 2.66% | -8 min | 5.8% | 977 |
| Republic Airways on ORD → PIT | 83.5% | 1.76% | -11 min | 6.4% | 3,473 |
| All ORD → PIT flights | 77.3% | 1.55% | -6 min | 8.7% | 10,269 |
YX3464 has cancelled 2.66% of its scheduled departures (26 of 977), against 1.55% for all ORD → PIT flights — this specific departure cancels 1.1 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 YX3464 specifically, not about the route it flies.

Why YX3464 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for YX3464 on ORD → PIT. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX3464 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX3464 pushed back an average of 27 minutes late; when it came in on time or early, an average of 6 minutes late.
Each departure is matched to the flight the same aircraft flew into ORD just before it, using the tail number in the DOT file, 737 of 951 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 |
|---|---|---|---|
| YX3464 | 21% | 38% | 11% |
| Network, same turn | 23% | 40% | 9% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often YX3464’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often YX3464 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves ORD late, does that still matter by the time it reaches PIT?
YX3464 pushes back an average of 10.7 minutes late and reaches the gate at PIT an average of 4.7 minutes late. The 6.0 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 24.7 minutes on the taxiways at ORD is about what any departure from the airport in that hour spends.
On arrival at PIT, YX3464 spends 6.0 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 PIT 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 PIT. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 36,773 departures from ORD scheduled in the clock hour YX3464 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at PIT (132,905 flights), not just YX3464’s own. More on taxi time.

The hour it leaves ORD
Part of any flight’s record belongs to the clock rather than to the flight. YX3464 has one departure time, so this is what that time is worth.
On-time arrival rate. 36,773 departures from ORD are scheduled in the 9 PM–10 PM hour over the period, against 952,802 across the whole day.
YX3464 is scheduled out of ORD at 9:05 PM, in the 9 PM–10 PM bank. Departures from ORD in that hour arrive on time 67.6% of the time against 74.5% across the airport’s whole day — the slot alone is worth 7.0 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from ORD 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.

By day of week
Does YX3464 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 10.8 percentage points.

Because the same number has served different journeys, the statistics above describe only the route YX3464 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 977 records of YX3464 operating ORD → PIT, 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.
