DL 711 lands a B+, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That is a workable record, not a spotless one. That rests on 360 flights, with a median arrival 3 minutes early.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 3 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 711 flies

DL 711 flies ATL to LAS without a single fixed slot. Its most common scheduled departure was 17:25, used on 62 of 360 flights, with 17:50 (56 flights) and 16:59 (42 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 17:25 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 711 runs 9 points better at 77.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 711 next to ATL to LAS

Across the year

DL 711 quarter by quarter

DL 711 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.4% on time and its weakest Jul–Sep 2025 at 69.6%, a swing of 13 points on roughly 90 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.

Oct–Dec 202587 flights79.1%
Jan–Mar 202690 flights78.9%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 711 did best on Wednesday at 88.0% on time and worst on Thursday at 66.0%. Each day rests on about 51 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 711 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,428 reported delay minutes.

Carrier
40%
National Airspace System
36%
Late-arriving aircraft
15%
Extreme weather
9%

The largest share of delay minutes, 40%, 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 1,779 of the 4,428 delay minutes reported here. The split is drawn from 4,428 delay minutes reported on DL 711.

Cancellations are rare at 0.28%, 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

7.0% 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 55 minutes, which a normal layover absorbs.

At 1,747 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 360 flights under DL 711 in the data flew ATL to LAS. 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. 360 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.
