These figures cover 274 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
DL 2613 quarter by quarter
DL 2613 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.5% on time and its weakest Oct–Dec 2025 at 69.9%, a swing of 22 points on roughly 69 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.

The worst days
Worst days for DL 2613
The latest arrival of the period was on 18 September 2025, 5 hours 26 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 September 2025 | 5 hours 26 minutes | Late-arriving aircraft |
| 21 November 2025 | 2 hours 1 minute | National Airspace System |
| 8 March 2026 | 1 hour 48 minutes | Carrier |
| 17 December 2025 | 1 hour 44 minutes | Late-arriving aircraft |
| 23 June 2026 | 1 hour 43 minutes | Late-arriving aircraft |
Delay causes
Why DL 2613 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 2,372 reported delay minutes.
- 38%Late-arriving aircraft
- 37%Carrier
- 25%National Airspace System
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,372 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 2,372 delay minutes reported on DL 2613.
Cancellations are rare at 0.73%, below the national 1.89% 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
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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.
DL 2613 is not only a SEA to SAN flight. It also flew SAN to SEA (268 flights, 84.5% 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. 274 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.
