These figures cover 365 flights between September 2025 and August 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.

Across the year
DL 435 quarter by quarter
DL 435 did not run the same all year. Its best quarter was Oct–Dec 2025 at 94.4% on time and its weakest Jan–Mar 2026 at 82.6%, a swing of 12 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202592 flights94.4%
- Jan–Mar 202690 flights82.6%
- Apr–Jun 202691 flights92.2%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 435 did best on Wednesday at 98.0% on time and worst on Saturday at 85.7%. Each day rests on about 52 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes
Why DL 435 runs late
Late-arriving aircraft accounts for 46% of the 2,142 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 34%Carrier
- 16%National Airspace System
- 4%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,142 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 2,142 delay minutes reported on DL 435.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.1% 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.
At 2,615 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 365 flights under DL 435 in the data flew LIH 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.
