Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2001, check with Delta Air Lines.

DL 2001 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 308 flights, with a median arrival 7 minutes early.

These figures cover 308 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 2001 flies

DL 2001 flies ATL to MEM without a single fixed slot. Its most common scheduled departure was 20:10, used on 60 of 308 flights, with 20:37 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:10 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2001 runs 7 points better at 77.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 2001 quarter by quarter

Quarter by quarter DL 2001 held fairly steady: 80.5% in Jul–Sep 2025, 79.7% in Oct–Dec 2025, 72.7% in Jan–Mar 2026 and 77.8% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202589 flights80.5%
Oct–Dec 202559 flights79.7%
Jan–Mar 202669 flights72.7%
Apr–Jun 202691 flights77.8%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2001 ranged from 73.9% on Friday to 82.9% on Saturday. With about 44 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2001 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 4,567 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.

National Airspace System

Late-arriving aircraft
18%
Extreme weather
5%

The largest share of delay minutes, 58%, 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 2,648 of the 4,567 delay minutes reported here. The split is drawn from 4,567 delay minutes reported on DL 2001.

Cancellations sit at 1.95% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.6% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including AGS to ATL (9), but none flew often enough under DL 2001 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. 308 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 2001

For a booking, read DL 2001 as 77.8% on time with 1.95% cancelled over 308 flights. Those are rates from the past twelve months, not a forecast for any particular day.
