These figures cover 301 flights between July 2025 and June 2026. The median arrival is 6 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.
Schedule

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 3885 runs 3 points better at 73.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
F9 3885 quarter by quarter
F9 3885 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.1% on time and its weakest Apr–Jun 2026 at 56.8%, a swing of 29 points on roughly 75 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 3885 did best on Wednesday at 94.3% on time and worst on Sunday at 62.0%. Each day rests on about 43 flights, so a gap of 32 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 3885 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 4,143 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.
- 51%Late-arriving aircraft
- 25%National Airspace System
- 18%Carrier
- 6%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,143 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,143 delay minutes reported on F9 3885.
Cancellations sit at 2.33% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.1% 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 roughly 55 minutes, which a normal layover absorbs.
The 1,055 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 301 flights under F9 3885 in the data flew DFW to LAS. 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. 301 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.
What to do with this
Booking F9 3885
