These figures cover 365 flights between September 2025 and August 2026. The median arrival is 4 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 443 quarter by quarter

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 April 2026 | 4 hours 41 minutes | Carrier |
| 21 December 2025 | 4 hours 28 minutes | Carrier |

Delay causes
Why DL 443 runs late
Carrier accounts for 67% of the 4,258 delay minutes carriers reported here, and the remaining four split what is left.
- 67%Carrier
- 20%Late-arriving aircraft
- 13%National Airspace System
The largest share of delay minutes, 67%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,853 of the 4,258 delay minutes reported here. The split is drawn from 4,258 delay minutes reported on DL 443.
Cancellations are rare at 0.27%, 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
6.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 2,556 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 443 in the data flew LAX to HNL. 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.
