Across the year
DL 2272 quarter by 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.

Share of 275 completed flights by arrival against schedule.
12 of 79 late departures made up the time and arrived on time, 15% of them. In the other direction, 40 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SFO.
The worst days
Worst days for DL 2272
The latest arrival of the period was on 22 October 2025, 4 hours 12 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as national airspace system delay.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 October 2025 | 4 hours 12 minutes | Carrier |
| 20 April 2026 | 4 hours 11 minutes | National Airspace System |

Delay causes
Why DL 2272 runs late
National Airspace System accounts for 70% of the 5,608 delay minutes carriers reported here, and the remaining four split what is left.
- 70%National Airspace System
- 20%Carrier
- 7%Late-arriving aircraft
- 2%Extreme weather
70% 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 3,924 minutes out of 5,608, against a national NAS share of 21%. The split is drawn from 5,608 delay minutes reported on DL 2272.
Cancellations sit at 1.43% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
9.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on two other city pairs in the data, including SFO to LAX (231) and LAS to MSP (85), but none flew often enough under DL 2272 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to SFO only.
One caution: this is a thin sample. 279 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 DL 2272
For a booking, read DL 2272 as 61.1% on time with 1.43% cancelled over 279 flights. Those are rates from the past twelve months, not a forecast for any particular day.
