Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2606, check with Delta Air Lines.

DL 2606 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 365 flights, with a median arrival 11 minutes early.

Set against the rest of the country, DL 2606's record is 7 points better than the US average of 77.6%. That gap is worth roughly 72 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 11 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 2606 flies

DL 2606 flies LAX to SEA without a single fixed slot. Its most common scheduled departure was 14:10, used on 98 of 365 flights, with 14:00 (66 flights) and 15:35 (60 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 14:10 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2606 runs 12 points better at 84.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 2606 next to LAX to SEA

Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 3 points.

Across the year

DL 2606 quarter by quarter

Quarter by quarter DL 2606 held fairly steady: 89.0% in Jul–Sep 2025, 85.4% in Oct–Dec 2025, 81.1% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights89.0%
Oct–Dec 202592 flights85.4%
Jan–Mar 202690 flights81.1%
Apr–Jun 202691 flights83.5%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2606 did best on Tuesday at 94.3% on time and worst on Sunday at 70.6%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2606 runs late

One category carries most of the weight here. Carrier accounts for 63% of the 4,239 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
63%
Late-arriving aircraft
31%
National Airspace System
6%

The largest share of delay minutes, 63%, 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 2,685 of the 4,239 delay minutes reported here. The split is drawn from 4,239 delay minutes reported on DL 2606.

Cancellations are rare at 0.82%, below the national 1.81% 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

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 a little over an hour, which a normal layover absorbs.

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 365 flights under DL 2606 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. 365 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 2606

For a booking, read DL 2606 as 84.8% on time with 0.82% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
