These figures cover 353 flights between September 2025 and August 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.

Across the year
DL 2408 quarter by quarter
DL 2408 did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.5% on time and its weakest Oct–Dec 2025 at 62.5%, a swing of 26 points on roughly 71 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 2408 did best on Sunday at 82.0% on time and worst on Wednesday at 66.7%. Each day rests on about 50 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2408 runs when it is late
DL 2408 often beats the schedule: 134 of 341 completed flights, 39%, arrived 15 minutes or more early. The 85 late arrivals split 34 under half an hour, 26 between 30 and 60 minutes, and 25 an hour or more.

Share of 341 completed flights by arrival against schedule.
26 of 87 late departures made up the time and arrived on time, 30% of them. In the other direction, 24 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 SEA.
The worst days
Worst days for DL 2408
The latest arrival of the period was on 23 December 2025, 17 hours 2 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 December 2025 | 17 hours 2 minutes | Carrier |
| 27 February 2026 | 15 hours 34 minutes | Carrier |
| 20 March 2026 | 13 hours 41 minutes | Carrier |
| 25 July 2026 | 13 hours 28 minutes | Carrier |
| 25 February 2026 | 11 hours 10 minutes | Late-arriving aircraft |
Delay causes
Why DL 2408 runs late
Carrier accounts for 59% of the 9,200 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 28%Late-arriving aircraft
- 11%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,441 of the 9,200 delay minutes reported here. The split is drawn from 9,200 delay minutes reported on DL 2408.
Cancellations run at 3.40%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
7.3% 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 close to two hours, which a normal layover absorbs.
At 1,533 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 353 flights under DL 2408 in the data flew FAI to SEA. 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. 353 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 2408
For a booking, the cancellation rate is the figure to plan around on DL 2408: 3.40% of its 353 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
