Why F91149 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 F91149 on MSP → DEN. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F91149 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91149 pushed back an average of 20 minutes late; when it came in on time or early, an average of 3 minutes early.
Each departure is matched to the flight the same aircraft flew into MSP just before it, using the tail number in the DOT file, 791 of 803 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 |
|---|---|---|---|
| F91149 | 26% | 31% | 5% |
| Network, same turn | 33% | 24% | 11% |
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 3 to 6 hours. How often F91149’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often F91149 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MSP late, does that still matter by the time it reaches DEN?
F91149 pushes back an average of 5.4 minutes late and reaches the gate at DEN an average of 1.8 minutes late. The 3.6 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. It spends 20.0 minutes on the taxiways at MSP, 1.6 minutes longer than a typical MSP departure in the same hour.
On arrival at DEN, F91149 spends 14.9 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 5.1 minutes longer than a typical DEN arrival (9.8 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 DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 15,010 departures from MSP scheduled in the clock hour F91149 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just F91149’s own. More on taxi time.

The hour it leaves MSP
Part of any flight’s record belongs to the clock rather than to the flight. F91149 has one departure time, so this is what that time is worth.
On-time arrival rate. 15,010 departures from MSP are scheduled in the 6 AM–7 AM hour over the period, against 369,781 across the whole day.
F91149 is scheduled out of MSP at 6:00 AM, in the 6 AM–7 AM bank. Departures from MSP in that hour arrive on time 89.7% of the time against 81.1% across the airport’s whole day — the slot alone is worth 8.6 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MSP 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 F91149 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 |
|---|---|---|---|
| PHL→MCO Philadelphia to Orlando | August 3–14, 2023 | 4 | — |
Because the same number has served different journeys, the statistics above describe only the route F91149 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 |
|---|---|---|---|---|
| F91149 this flight | Frontier Airlines | 83.8% | 11 min early | 809 |
| DL1025 | Delta Air Lines | 76.1% | 3 min early | 785 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. F91149 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 809 records of F91149 operating MSP → DEN, 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.
