| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| F91080 | 69.2% | 2.92% | -2 min | 10.4% | 616 |
| Frontier Airlines on ATL → BWI | 61.5% | 3.32% | 4 min | 16.4% | 2,438 |

Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about F91080 specifically, not about the route it flies.
10.4% of F91080’s arrivals were an hour or more late, against 8.7% across ATL → BWI, so the long delays are more common on this number than on the route.

Why F91080 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 F91080 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91080 pushed back an average of 34 minutes late; when it came in on time or early, an average of 2 minutes late.
Matched by tail number to the aircraft’s previous flight into ATL: 530 of 601 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 |
|---|---|---|---|
| F91080 | 31% | 58% | 13% |
| Network, same turn | 17% | 69% | 9% |
67 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 60 to 89 minutes. How often F91080’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F91080 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves ATL late, does that still matter by the time it reaches BWI?
F91080 pushes back an average of 17.0 minutes late and reaches the gate at BWI an average of 14.3 minutes late. The 2.7 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 20.7 minutes on the taxiways at ATL, 5.8 minutes longer than a typical ATL departure in the same hour.
On arrival at BWI, F91080 spends 10.4 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 4.4 minutes longer than a typical BWI arrival (6.0 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 56,837 ATL departures. Taxi-in is landing to gate, set against 307,150 arrivals at BWI. More on taxi time.
