These figures cover 331 flights between July 2025 and June 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 1149 runs 7 points worse at 82.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
F9 1149 quarter by quarter
F9 1149 did not run the same all year. Its best quarter was Jul–Sep 2025 at 91.3% on time and its weakest Apr–Jun 2026 at 77.2%, a swing of 14 points on roughly 83 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, F9 1149 did best on Thursday at 95.7% on time and worst on Wednesday at 72.9%. Each day rests on about 47 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 1149 runs late
One category carries most of the weight here. Carrier accounts for 50% of the 5,527 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 50%Carrier
- 25%Late-arriving aircraft
- 24%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,762 of the 5,527 delay minutes reported here. The split is drawn from 5,527 delay minutes reported on F9 1149.
Cancellations are rare at 0.60%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.9% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 680 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 331 flights under F9 1149 in the data flew MSP to DEN. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 331 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
