These figures cover 348 flights between September 2025 and August 2026. The median arrival is 7 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 1682 quarter by quarter
DL 1682 did not run the same all year. Its best quarter was Jul–Sep 2026 at 91.8% on time and its weakest Oct–Dec 2025 at 80.2%, a swing of 12 points on roughly 87 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.

By weekday, DL 1682 did best on Wednesday at 93.5% on time and worst on Saturday at 75.0%. Each day rests on about 50 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes
Why DL 1682 runs late
Carrier accounts for 57% of the 2,776 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 28%National Airspace System
- 14%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,590 of the 2,776 delay minutes reported here. The split is drawn from 2,776 delay minutes reported on DL 1682.
Cancellations sit at 1.44% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and routes
What a delay on this flight costs
5.0% 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 roughly 50 minutes, which a normal layover absorbs.
The 689 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
DL 1682 is not only a ATL to IAH flight. It also flew IAH to ATL (345 flights, 78.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 348 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.
