These figures cover 363 flights between September 2025 and August 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:35 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2975 runs level with that at 89.5%. 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 2975 quarter by quarter

|---|---|---|
| 19 November 2025 | 3 hours 12 minutes | Carrier |

Delay causes
Why DL 2975 runs late
Carrier accounts for 94% of the 2,093 delay minutes carriers reported here, and the remaining four split what is left.
- 94%Carrier
- 5%National Airspace System
- 1%Late-arriving aircraft
The largest share of delay minutes, 94%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,969 of the 2,093 delay minutes reported here. The split is drawn from 2,093 delay minutes reported on DL 2975.
Cancellations run at 3.31%, against 1.89% 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
Badly late arrivals are rare here: only 3.7% land an hour or more behind schedule, against 8.3% 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.
DL 2975 is not only a LAX to PDX flight. It also flew PDX to LAX (363 flights, 89.8% 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. 363 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.
