Historical statistics for July 2025 to June 2026, not live status. For today’s DL 682, check with Delta Air Lines.
DL 682 lands a B+, 4 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 357 flights, with a median arrival 3 minutes early.

These figures cover 357 flights between July 2025 and June 2026. The median arrival is 3 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 682 flies
DL 682 flies ATL to SMF without a single fixed slot. Its most common scheduled departure was 20:59, used on 113 of 357 flights, with 20:20 (55 flights) and 20:50 (39 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 20:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 682 runs 11 points better at 81.3%. 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 682 quarter by quarter
Quarter by quarter DL 682 held fairly steady: 84.4% in Jul–Sep 2025, 80.5% in Oct–Dec 2025, 78.4% in Jan–Mar 2026 and 81.8% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202588 flights80.5%
- Jan–Mar 202689 flights78.4%
- Apr–Jun 202688 flights81.8%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 682 did best on Saturday at 87.8% on time and worst on Thursday at 72.9%. Each day rests on about 51 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 682 runs late
One category carries most of the weight here. Carrier accounts for 53% of the 3,816 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.
- 53%Carrier
- 19%Late-arriving aircraft
- 18%National Airspace System
- 9%Extreme weather
The largest share of delay minutes, 53%, 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 2,035 of the 3,816 delay minutes reported here. The split is drawn from 3,816 delay minutes reported on DL 682.
Cancellations are rare at 0.84%, below the national 1.81% 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 4.2% 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 2,092 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 357 flights under DL 682 in the data flew ATL to SMF. 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. 357 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.
