These figures cover 363 flights between September 2025 and August 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 April 2026 | 3 hours 54 minutes | Carrier |
| 4 November 2025 | 3 hours 38 minutes | Carrier |

Delay causes
Why DL 2766 runs late
Carrier accounts for 80% of the 2,699 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Carrier
- 17%Late-arriving aircraft
- 3%National Airspace System
The largest share of delay minutes, 80%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,166 of the 2,699 delay minutes reported here. The split is drawn from 2,699 delay minutes reported on DL 2766.
Cancellations are rare at 0.28%, below the national 1.89% 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 3.6% 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 2766 is not only a LAX to PDX flight. It also flew PDX to LAX (362 flights, 91.1% 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.
