F9 1994 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 6 points better than the national rate of 77.6%.

These figures cover 336 flights between July 2025 and June 2026. The median arrival is 15 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 1994 flies

F9 1994 is scheduled to leave Las Vegas (LAS) at 00:59 local time and reach Denver (DEN) at 04:00. That slot held for 276 of the 336 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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

A 00:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 1994 runs 14 points better at 84.0%. 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 1994 quarter by quarter

F9 1994 did not run the same all year. Its best quarter was Oct–Dec 2025 at 88.2% on time and its weakest Apr–Jun 2026 at 75.6%, a swing of 13 points on roughly 84 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 1994 did best on Wednesday at 95.5% on time and worst on Tuesday at 75.0%. Each day rests on about 48 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 1994 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 3,762 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.

62%

34%

Extreme weather
1%

62% 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 3,762 reported delay minutes here, that single category outweighs weather by 62 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 3,762 delay minutes reported on F9 1994.

Cancellations are rare at 0.89%, 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

6.3% 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 a little over 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 336 flights under F9 1994 in the data flew LAS 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. 336 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 1994

For a booking, read F9 1994 as 84.0% on time with 0.89% cancelled over 336 flights. Those are rates from the past twelve months, not a forecast for any particular day.
