What stands out
How YX3545 compares to other flight numbers, not just to itself.
Every day of the week performs about the same on this flight, steadier than 99% of 1,710 comparable flight numbers.
81.3% on time on the best day (Tuesday) against 78.5% on the worst (Sunday).

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX3545 | 80.3% | 5.46% | -12 min | 6.7% | 898 |
| Republic Airways on EWR → CMH | 84.2% | 4.37% | -14 min | 6.6% | 5,656 |
| All EWR → CMH flights | 84.1% | 4.37% | -14 min | 6.6% | 5,949 |
YX3545 has cancelled 5.46% of its scheduled departures (49 of 898), against 4.37% for all EWR → CMH 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 YX3545 specifically, not about the route it flies.

Why YX3545 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
Share of the delay minutes US DOT attributed to each cause for YX3545 on EWR → CMH. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies YX3545 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX3545 pushed back an average of 32 minutes late; when it came in on time or early, an average of 1 minute late.
Each departure is matched to the flight the same aircraft flew into EWR just before it, using the tail number in the DOT file, 738 of 852 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 |
|---|---|---|---|
| YX3545 | 18% | 45% | 6% |
| Network, same turn | 17% | 68% | 9% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often YX3545’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often YX3545 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves EWR late, does that still matter by the time it reaches CMH?
YX3545 pushes back an average of 11.3 minutes late and reaches the gate at CMH an average of 4.5 minutes late. The 6.8 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 27.0 minutes on the taxiways at EWR is about what any departure from the airport in that hour spends.
On arrival at CMH, YX3545 spends 9.9 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 2.6 minutes longer than a typical CMH arrival (7.3 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 CMH. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 22,983 departures from EWR scheduled in the clock hour YX3545 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at CMH (134,023 flights), not just YX3545’s own. More on taxi time.

The hour it leaves EWR
Part of any flight’s record belongs to the clock rather than to the flight. YX3545 has one departure time, so this is what that time is worth.
On-time arrival rate. 22,983 departures from EWR are scheduled in the 5 PM–6 PM hour over the period, against 387,621 across the whole day.
YX3545 is scheduled out of EWR at 5:30 PM, in the 5 PM–6 PM bank. Departures from EWR in that hour arrive on time 69.9% of the time against 77.7% across the airport’s whole day — the slot alone is worth 7.8 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from EWR 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 YX3545 run worse on particular days?
Tuesday is historically the most reliable day and Sunday the least, a gap of 2.8 percentage points.

Because the same number has served different journeys, the statistics above describe only the route YX3545 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. YX3545 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 898 records of YX3545 operating EWR → CMH, 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.
