F9 1993 lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 323 flights, with a median arrival 5 minutes early.

These figures cover 323 flights between July 2025 and June 2026. The median arrival is 5 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

When F9 1993 flies

F9 1993 flies DEN to LAS without a single fixed slot. Its most common scheduled departure was 10:00, used on 60 of 323 flights, with 10:01 (46 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and F9 1993 runs 6 points worse at 78.0%. 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 1993 quarter by quarter

F9 1993 did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.6% on time and its weakest Jul–Sep 2025 at 65.0%, a swing of 21 points on roughly 81 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 1993 did best on Wednesday at 87.5% on time and worst on Friday at 71.1%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 1993 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 4,294 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.

Extreme weather
2%

53% 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 4,294 reported delay minutes here, that single category outweighs weather by 33 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 4,294 delay minutes reported on F9 1993.

Cancellations are rare at 0.31%, 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

5.3% 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 about an hour, which a normal layover absorbs.

The 628 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 323 flights under F9 1993 in the data flew DEN 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. 323 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 1993

For a booking, read F9 1993 as 78.0% on time with 0.31% cancelled over 323 flights. Those are rates from the past twelve months, not a forecast for any particular day.
