These figures cover 359 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
DL 2672 quarter by quarter
DL 2672 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.7% on time and its weakest Jul–Sep 2026 at 63.3%, a swing of 23 points on roughly 90 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 2672 did best on Tuesday at 88.0% on time and worst on Sunday at 62.0%. Each day rests on about 51 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Share of 352 completed flights by arrival against schedule.
16 of 82 late departures made up the time and arrived on time, 20% of them. In the other direction, 25 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 SAN.

Delay causes
Why DL 2672 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,551 reported delay minutes.
- 33%Carrier
- 32%National Airspace System
- 29%Late-arriving aircraft
- 5%Extreme weather
No single cause dominates. carrier at 33%, national airspace system at 32% and late-arriving aircraft at 29% split the 4,551 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 4,551 delay minutes reported on DL 2672.
Cancellations sit at 1.11% against a national 1.89%, which is ordinary. Diversions add another 0.84%.
Connections and routes
What a delay on this flight costs
6.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 50 minutes, which a normal layover absorbs.
The 1,050 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.
Every one of the 359 flights under DL 2672 in the data flew SEA to SAN. 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. 359 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
