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 62.0% on Thursday to 72.0% on Wednesday. With about 37 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 252 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 75 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 15 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 MEM.

The worst days

Worst days for DL 1080

The latest arrival of the period was on 23 July 2026, 3 hours 56 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why DL 1080 runs late

Late-arriving aircraft accounts for 52% of the 4,916 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft

Carrier
37%

52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,916 reported delay minutes here, that single category outweighs weather by 52 to one. The split is drawn from 4,916 delay minutes reported on DL 1080.

Cancellations sit at 1.17% against a national 1.89%, which is ordinary. Diversions add another 0.39%.

Connections and routes

What a delay on this flight costs

13.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 256 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. 256 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. 13.5% 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.
