Historical statistics for July 2025 to June 2026, not live status. For today’s DL 916, check with Delta Air Lines.

DL 916 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 340 flights, with a median arrival right on schedule.

The national on-time rate over the same period is 77.6%, so DL 916 runs 5 points behind the country as a whole. Across a thousand flights that is about 49 extra late arrivals.

These figures cover 340 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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 916 flies

DL 916 flies DTW to LAS without a single fixed slot. Its most common scheduled departure was 20:15, used on 51 of 340 flights, with 20:40 (44 flights) and 20:30 (38 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 20:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 916 runs 2 points better at 72.7%. 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 916 quarter by quarter

DL 916 did not run the same all year. Its best quarter was Oct–Dec 2025 at 78.5% on time and its weakest Jan–Mar 2026 at 67.4%, a swing of 11 points on roughly 85 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.

By weekday, DL 916 did best on Tuesday at 84.4% on time and worst on Monday at 66.7%. Each day rests on about 49 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 916 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 5,929 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.

The largest share of delay minutes, 60%, 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 3,552 of the 5,929 delay minutes reported here. The split is drawn from 5,929 delay minutes reported on DL 916.

Cancellations are rare at 0.88%, 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

8.3% 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 an hour, which a normal layover absorbs.

At 1,749 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 340 flights under DL 916 in the data flew DTW 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. 340 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.
