These figures cover 339 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.

The worst days
Worst days for DL 682
The latest arrival of the period was on 14 December 2025, 12 hours 36 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 12 hours 36 minutes | Carrier |
| 20 July 2026 | 3 hours 10 minutes | Carrier |
| 14 June 2026 | 2 hours 26 minutes | Late-arriving aircraft |
| 8 November 2025 | 2 hours 11 minutes | National Airspace System |

Delay causes
Why DL 682 runs late
Carrier accounts for 59% of the 3,680 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 19%Late-arriving aircraft
- 18%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,173 of the 3,680 delay minutes reported here. The split is drawn from 3,680 delay minutes reported on DL 682.
Cancellations are rare at 0.59%, 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 4.2% 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 2,092 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 339 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. 339 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.
