These figures cover 300 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.

Across the year
DL 1381 quarter by quarter
DL 1381 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.8% on time and its weakest Jul–Sep 2026 at 70.0%, a swing of 20 points on roughly 75 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.

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1381 did best on Tuesday at 87.2% on time and worst on Saturday at 73.0%. Each day rests on about 43 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Share of 294 completed flights by arrival against schedule.
8 of 44 late departures made up the time and arrived on time, 18% of them. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CHS.

Connections and routes
What a delay on this flight costs
5.4% 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 about 50 minutes, which a normal layover absorbs.
DL 1381 is not only a ATL to CHS flight. It also flew CHS to ATL (251 flights, 81.2% 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. 300 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.
