Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1381, check with Delta Air Lines.

DL 1381 lands a B, 6 points better than the national rate of 77.6%. About one flight in six 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 275 flights, with a median arrival 5 minutes early.

Set against the rest of the country, DL 1381's record is 6 points better than the US average of 77.6%. That gap is worth roughly 57 fewer late arrivals for every thousand flights.

These figures cover 275 flights between July 2025 and June 2026. The median arrival is 5 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 1381 flies

DL 1381 flies ATL to CHS without a single fixed slot. Its most common scheduled departure was 14:41, used on 61 of 275 flights, with 14:59 (33 flights) and 21:49 (28 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 14:41 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1381 runs 11 points better at 83.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 1381 next to ATL to CHS

Every carrier on ATL to CHS combined arrived on time 83.7% of the time across 3,213 flights, so DL 1381 is about level with it. Delta flew 3,210 flights on the same city pair under all its flight numbers, including this one, and those ran 83.7% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 2 points.

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 Jan–Mar 2026 at 76.7%, a swing of 13 points on roughly 69 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 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1381 did best on Wednesday at 91.2% on time and worst on Saturday at 75.0%. Each day rests on about 39 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1381 runs late

One category carries most of the weight here. Carrier accounts for 65% of the 3,014 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.

The largest share of delay minutes, 65%, 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 1,945 of the 3,014 delay minutes reported here. The split is drawn from 3,014 delay minutes reported on DL 1381.

Cancellations sit at 1.82% against a national 1.81%, which is ordinary. Diversions add another 0.36%.

Connections and routes

What a delay on this flight costs

5.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including CHS to ATL (189), but none flew often enough under DL 1381 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to CHS only.

One caution: this is a thin sample. 275 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 1381

For a booking, read DL 1381 as 83.3% on time with 1.82% cancelled over 275 flights. Those are rates from the past twelve months, not a forecast for any particular day.
