DL 2408 lands a B−, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 361 flights, with a median arrival 10 minutes early.

These figures cover 361 flights between July 2025 and June 2026. The median arrival is 10 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 2408 flies

DL 2408 flies FAI to SEA without a single fixed slot. Its most common scheduled departure was 01:30, used on 113 of 361 flights, with 01:50 (109 flights) and 01:45 (55 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 01:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2408 runs 7 points better at 77.0%. 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 2408 next to FAI to SEA

Every carrier on FAI to SEA combined arrived on time 82.7% of the time across 2,320 flights, so DL 2408 is 6 points behind it. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 5 points.

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 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 2408 did best on Sunday at 84.0% on time and worst on Wednesday at 69.4%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2408 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 8,731 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.

Extreme weather

The largest share of delay minutes, 55%, 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 4,824 of the 8,731 delay minutes reported here. The split is drawn from 8,731 delay minutes reported on DL 2408.

Cancellations run at 3.60%, against 1.81% 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

7.5% 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 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 361 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. 361 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: 3.60% of its 361 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.
