Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2980, check with Delta Air Lines.

DL 2980 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 364 flights, with a median arrival 17 minutes early.

Set against the rest of the country, DL 2980's record is 14 points better than the US average of 77.6%. That gap is worth roughly 143 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 17 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 2980 flies

DL 2980 flies LAX to SEA without a single fixed slot. Its most common scheduled departure was 07:00, used on 160 of 364 flights, with 07:20 (80 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2980 runs 3 points better at 91.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 2980 quarter by quarter

Quarter by quarter DL 2980 held fairly steady: 91.3% in Jul–Sep 2025, 96.7% in Oct–Dec 2025, 89.8% in Jan–Mar 2026 and 89.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2980 ranged from 88.2% on Friday to 94.1% on Saturday. With about 52 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2980 runs late

One category carries most of the weight here. Carrier accounts for 83% of the 3,378 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.

Carrier
83%
Late-arriving aircraft
9%
National Airspace System
8%

The largest share of delay minutes, 83%, 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 2,802 of the 3,378 delay minutes reported here. The split is drawn from 3,378 delay minutes reported on DL 2980.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.1% 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 954 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 364 flights under DL 2980 in the data flew LAX 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. 364 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 2980

For a booking, DL 2980 has one of the better records a US domestic flight can show: 91.9% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
