Historical statistics for July 2025 to June 2026, not live status. For today’s DL 394, check with Delta Air Lines.
DL 394 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 18 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 365 flights, with a median arrival 21 minutes early.
Set against the rest of the country, DL 394's record is 18 points better than the US average of 77.6%. That gap is worth roughly 177 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 21 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 394 flies
DL 394 flies OGG to SEA without a single fixed slot. Its most common scheduled departure was 22:00, used on 96 of 365 flights, with 21:09 (80 flights) and 21:45 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 22:0096 flights26.3%
- Departs 21:0980 flights21.9%
- Departs 21:4541 flights11.2%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 394 runs 25 points better at 95.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 394 quarter by quarter
Quarter by quarter DL 394 held fairly steady: 97.8% in Jul–Sep 2025, 94.5% in Oct–Dec 2025, 94.3% in Jan–Mar 2026 and 94.5% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights97.8%
- Oct–Dec 202592 flights94.5%
- Jan–Mar 202690 flights94.3%
- Apr–Jun 202691 flights94.5%
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 394 ranged from 92.0% on Sunday to 98.1% on Thursday. With about 52 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 394 runs late
One category carries most of the weight here. Carrier accounts for 75% of the 1,597 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.
- 75%Carrier
- 15%Late-arriving aircraft
- 10%National Airspace System
The largest share of delay minutes, 75%, 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 1,197 of the 1,597 delay minutes reported here. The split is drawn from 1,597 delay minutes reported on DL 394.
Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 0.8% 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.
At 2,639 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 394 in the data flew OGG to SEA. 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.
