Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1681, check with Delta Air Lines.

DL 1681 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 roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 290 flights, with a median arrival 6 minutes early.

Set against the rest of the country, DL 1681's record is 6 points better than the US average of 77.6%. That gap is worth roughly 58 fewer late arrivals for every thousand flights.

These figures cover 290 flights between July 2025 and June 2026. The median arrival is 6 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 1681 flies

DL 1681 flies ATL to MEM without a single fixed slot. Its most common scheduled departure was 14:05, used on 36 of 290 flights, with 16:42 (33 flights) and 13:26 (31 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 14:05 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1681 runs 11 points better at 83.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1681 quarter by quarter

DL 1681 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.3% on time and its weakest Jul–Sep 2025 at 73.4%, a swing of 16 points on roughly 73 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.

Jul–Sep 202564 flights73.4%
Oct–Dec 202557 flights89.3%
Jan–Mar 202681 flights84.6%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1681 did best on Tuesday at 88.9% on time and worst on Monday at 72.1%. Each day rests on about 41 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1681 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 2,288 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.

Extreme weather
2%

The largest share of delay minutes, 55%, 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 1,264 of the 2,288 delay minutes reported here. The split is drawn from 2,288 delay minutes reported on DL 1681.

Cancellations sit at 2.41% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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 8.1% 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 same number turns up on two other city pairs in the data, including MEM to ATL (227) and FLL to JFK (16), but none flew often enough under DL 1681 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MEM only.

One caution: this is a thin sample. 290 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 1681

For a booking, read DL 1681 as 83.4% on time with 2.41% cancelled over 290 flights. Those are rates from the past twelve months, not a forecast for any particular day.
