Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2613, check with Delta Air Lines.

DL 2613 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 267 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 2613's record is 6 points better than the US average of 77.6%. That gap is worth roughly 57 fewer late arrivals for every thousand flights.

These figures cover 267 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 2613 flies

DL 2613 flies SAN to SEA without a single fixed slot. Its most common scheduled departure was 19:10, used on 59 of 267 flights, with 19:15 (55 flights) and 19:05 (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 19:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2613 runs 15 points better at 83.3%. 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 2613 next to SAN to SEA

Every carrier on SAN to SEA combined arrived on time 80.8% of the time across 4,582 flights, so DL 2613 is 3 points ahead of it. Delta flew 1,700 flights on the same city pair under all its flight numbers, including this one, and those ran 87.3% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 2 points.

Across the year

DL 2613 quarter by quarter

DL 2613 did not run the same all year. Its best quarter was Jan–Mar 2026 at 95.7% on time and its weakest Oct–Dec 2025 at 73.5%, a swing of 22 points on roughly 67 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 2613 did best on Monday at 92.9% on time and worst on Thursday at 73.7%. Each day rests on about 38 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2613 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 4,311 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
57%
Carrier
31%
National Airspace System
12%

57% 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 4,311 reported delay minutes here, that single category outweighs weather by 57 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 4,311 delay minutes reported on DL 2613.

Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.2% 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 an hour and a half, 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.

DL 2613 is not only a SAN to SEA flight. It also flew SEA to SAN (264 flights, 80.8% 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. 267 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.
