Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX5777 | 79.5% | 0.81% | -10 min | 9.1% | 620 |
| Republic Airways on DCA → BNA | 84.6% | 1.69% | -11 min | 5.4% | 5,203 |
| All DCA → BNA flights | 78.8% | 2.60% | -7 min | 8.1% | 13,220 |
YX5777 has cancelled 0.81% of its scheduled departures (5 of 620), against 2.60% for all DCA → BNA flights — this specific departure cancels 1.8 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 YX5777 specifically, not about the route it flies.

Why YX5777 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
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
Share of the delay minutes US DOT attributed to each cause for YX5777 on DCA → BNA. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies YX5777 comes in late, and what that does to the departure.
The aircraft flying YX5777 came in 15 or more minutes late on 18% 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.
Matched by tail number to the aircraft’s previous flight into DCA: 604 of 616 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 |
|---|---|
| YX5777 | 18% |
| Network, same turn | 18% |
Little slack sits between the inbound landing and this departure, so a late arrival has almost nowhere to go but into the departure.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often YX5777’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DCA late, does that still matter by the time it reaches BNA?
YX5777 pushes back an average of 9.7 minutes late and reaches the gate at BNA an average of 6.0 minutes late. The 3.7 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 21.3 minutes on the taxiways at DCA, 2.4 minutes shorter than a typical DCA departure in the same hour.
On arrival at BNA, YX5777 spends 11.3 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 3.4 minutes longer than a typical BNA arrival (7.9 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 31,388 DCA departures. Taxi-in is landing to gate, set against 329,326 arrivals at BNA. More on taxi time.

The hour it leaves DCA
YX5777 has one departure time, 3:40 PM, so this is what that hour at DCA is worth.
On-time arrival rate. 31,388 departures from DCA are scheduled in the 3 PM–4 PM hour over the period, against 447,230 across the whole day.
YX5777 is scheduled out of DCA at 3:40 PM, in the 3 PM–4 PM bank. Departures from DCA in that hour arrive on time 72.0% of the time against 76.3% across the airport’s whole day — the slot alone is worth 4.3 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from DCA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 620 records of YX5777 operating DCA → BNA, 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.
