These figures cover 341 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% 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 DL 2272 flies

DL 2272 flies LAX to SFO without a single fixed slot. Its most common scheduled departure was 10:00, used on 57 of 341 flights, with 10:15 (40 flights) and 10:40 (39 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 DL 2272 runs 21 points worse at 62.9%. 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

DL 2272 quarter by quarter

DL 2272 did not run the same all year. Its best quarter was Jan–Mar 2026 at 75.3% on time and its weakest Apr–Jun 2026 at 43.8%, a swing of 32 points on roughly 85 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, DL 2272 did best on Saturday at 70.2% on time and worst on Friday at 51.1%. Each day rests on about 49 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2272 runs late

One category carries most of the weight here. National Airspace System accounts for 67% of the 6,553 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%

67% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,390 minutes out of 6,553, against a national NAS share of 21%. The split is drawn from 6,553 delay minutes reported on DL 2272.

Cancellations sit at 1.17% 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. 9.2% 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.

DL 2272 is not only a LAX to SFO flight. It also flew SFO to LAX (293 flights, 67.8% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 341 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.
