These figures cover 254 flights between September 2025 and August 2026. The median arrival is 14 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 1676 quarter by quarter
DL 1676 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.3% on time and its weakest Jul–Sep 2026 at 84.7%, a swing of 11 points on roughly 85 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 1676 did best on Wednesday at 97.1% on time and worst on Monday at 82.9%. Each day rests on about 36 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 1676
The latest arrival of the period was on 12 July 2026, 1 hour 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 |
|---|---|---|
| 12 July 2026 | 1 hour 36 minutes | Carrier |
| 7 March 2026 | 1 hour | Carrier |

Delay causes
Why DL 1676 runs late
Carrier accounts for 55% of the 744 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 25%National Airspace System
- 13%Late-arriving aircraft
- 8%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 408 of the 744 delay minutes reported here. The split is drawn from 744 delay minutes reported on DL 1676.
Cancellations run at 5.12%, against 1.89% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
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 8.3% 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.
The 874 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 1676 is not only a ATL to SAT flight. It also flew SAT to ATL (254 flights, 86.7% 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. 254 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.

What to do with this
Booking DL 1676
