These figures cover 365 flights between July 2025 and June 2026. The median arrival is 14 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 2947 flies

DL 2947 flies PDX to LAX without a single fixed slot. Its most common scheduled departure was 06:15, used on 75 of 365 flights, with 06:29 (64 flights) and 06:25 (47 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 06:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2947 runs 5 points better at 94.5%. 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 2947 quarter by quarter

Quarter by quarter DL 2947 held fairly steady: 96.7% in Jul–Sep 2025, 91.3% in Oct–Dec 2025, 94.4% in Jan–Mar 2026 and 95.6% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights96.7%
Oct–Dec 202592 flights91.3%
Jan–Mar 202690 flights94.4%
Apr–Jun 202691 flights95.6%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2947 ranged from 90.4% on Sunday to 98.1% on Monday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2947 runs late

One category carries most of the weight here. Carrier accounts for 67% of the 2,889 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
67%
Late-arriving aircraft
25%
National Airspace System
8%

The largest share of delay minutes, 67%, 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 1,927 of the 2,889 delay minutes reported here. The split is drawn from 2,889 delay minutes reported on DL 2947.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 2.2% 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 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.

Every one of the 365 flights under DL 2947 in the data flew PDX to LAX. 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 2947

For a booking, DL 2947 has one of the better records a US domestic flight can show: 94.5% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
