DL 1080 draws a C+. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 254 flights, with a median arrival 2 minutes late.

The national on-time rate over the same period is 77.6%, so DL 1080 runs 10 points behind the country as a whole. Across a thousand flights that is about 99 extra late arrivals.

These figures cover 254 flights between July 2025 and June 2026. Beyond the headline rate, 12.7% 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 1080 flies

DL 1080 flies LAX to MEM without a single fixed slot. Its most common scheduled departure was 18:15, used on 56 of 254 flights, with 18:30 (55 flights) and 18:14 (39 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 18:15 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1080 runs level with that at 67.7%. 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 1080 quarter by quarter

DL 1080 did not run the same all year. Its best quarter was Oct–Dec 2025 at 71.9% on time and its weakest Jan–Mar 2026 at 61.7%, a swing of 10 points on roughly 64 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 55% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1080 ranged from 64.0% on Thursday to 69.6% on Sunday. With about 36 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1080 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 4,757 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.

53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,757 reported delay minutes here, that single category outweighs weather by 53 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,757 delay minutes reported on DL 1080.

Cancellations are rare at 0.79%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 1,619 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 254 flights under DL 1080 in the data flew LAX to MEM. The number was not reused on any other city pair, which makes this a clean record of one route.

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 1080

For a booking, DL 1080 is a flight to put a long connection behind. 12.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
