Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2672, check with Delta Air Lines.
DL 2672 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 359 flights, with a median arrival 1 minute early.

These figures cover 359 flights between July 2025 and June 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.
Schedule
When DL 2672 flies
DL 2672 flies SEA to SAN without a single fixed slot. Its most common scheduled departure was 19:35, used on 160 of 359 flights, with 19:55 (68 flights) and 19:45 (50 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 19:35 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2672 runs 8 points better at 76.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
DL 2672 next to SEA to SAN

Delta flew 1,700 flights on the same city pair under all its flight numbers, including this one, and those ran 82.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 5 points.

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 Jan–Mar 2026 at 64.4%, a swing of 22 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.

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2672 did best on Monday at 82.4% on time and worst on Sunday at 68.0%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
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 4,114 reported delay minutes.
- 38%Carrier
- 31%National Airspace System
- 25%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,571 of the 4,114 delay minutes reported here. The split is drawn from 4,114 delay minutes reported on DL 2672.
Cancellations are rare at 0.84%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.6% 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 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. 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 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
Booking DL 2672
