These figures cover 289 flights between July 2025 and June 2026. Beyond the headline rate, 9.4% 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 3211 flies

F9 3211 flies DFW to LAX without a single fixed slot. Its most common scheduled departure was 16:39, used on 48 of 289 flights. 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 16:39 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and F9 3211 runs 3 points better at 75.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

F9 3211 quarter by quarter

F9 3211 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.6% on time and its weakest Jul–Sep 2025 at 68.1%, a swing of 17 points on roughly 72 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 3211 did best on Wednesday at 82.9% on time and worst on Sunday at 68.2%. Each day rests on about 41 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 3211 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 69% of the 5,600 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
69%
Carrier
18%
National Airspace System
12%
Extreme weather
1%

69% 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 5,600 reported delay minutes here, that single category outweighs weather by 58 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 5,600 delay minutes reported on F9 3211.

Cancellations sit at 1.04% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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 289 flights under F9 3211 in the data flew DFW to LAX. 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. 289 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 3211
