DL 2766 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 11 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 362 flights, with a median arrival 15 minutes early.

Set against the rest of the country, DL 2766's record is 11 points better than the US average of 77.6%. That gap is worth roughly 110 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 15 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 2766 flies

DL 2766 flies LAX to PDX without a single fixed slot. Its most common scheduled departure was 09:45, used on 60 of 362 flights, with 08:45 (40 flights) and 10:00 (38 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 09:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2766 runs 5 points better at 88.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

DL 2766 quarter by quarter

Quarter by quarter DL 2766 held fairly steady: 92.1% in Jul–Sep 2025, 90.2% in Oct–Dec 2025, 88.5% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2766 ranged from 82.7% on Monday to 92.3% on Wednesday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2766 runs late

One category carries most of the weight here. Carrier accounts for 78% of the 3,187 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
78%
Late-arriving aircraft
19%
National Airspace System
3%

The largest share of delay minutes, 78%, 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 2,475 of the 3,187 delay minutes reported here. The split is drawn from 3,187 delay minutes reported on DL 2766.

Cancellations are rare at 0.83%, 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

Badly late arrivals are rare here: only 4.5% 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 833 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.

DL 2766 is not only a LAX to PDX flight. It also flew PDX to LAX (361 flights, 91.6% 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. 362 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.
