These figures cover 281 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When F9 4964 flies

F9 4964 flies LAX to DFW without a single fixed slot. Its most common scheduled departure was 19:03, used on 48 of 281 flights, with 19:00 (39 flights) and 05:45 (35 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 19:03 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and F9 4964 runs 6 points better at 74.2%. 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 4964 quarter by quarter

Quarter by quarter F9 4964 held fairly steady: 73.6% in Jul–Sep 2025, 71.4% in Oct–Dec 2025, 70.5% in Jan–Mar 2026 and 78.7% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, F9 4964 did best on Thursday at 81.8% on time and worst on Monday at 63.5%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4964 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 7,477 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.

Late-arriving aircraft
54%
Carrier
37%
National Airspace System
8%
Extreme weather
1%

54% 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 7,477 reported delay minutes here, that single category outweighs weather by 54 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 7,477 delay minutes reported on F9 4964.

Cancellations sit at 1.78% against a national 1.81%, which is ordinary. Diversions add another 0.36%.

Connections and routes

What a delay on this flight costs

8.7% 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 close to two hours, which a normal layover absorbs.

The 1,235 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 281 flights under F9 4964 in the data flew LAX to DFW. 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. 281 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 4964
