DL 883 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 346 flights, with a median arrival 4 minutes early.

These figures cover 346 flights between July 2025 and June 2026. The median arrival is 4 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 883 flies

DL 883 flies DTW to LAX without a single fixed slot. Its most common scheduled departure was 16:00, used on 52 of 346 flights, with 15:50 (46 flights) and 18:59 (36 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 16:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 883 runs 4 points better at 76.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

Across the year

DL 883 quarter by quarter

Quarter by quarter DL 883 held fairly steady: 81.1% in Jul–Sep 2025, 71.4% in Oct–Dec 2025, 78.7% in Jan–Mar 2026 and 75.8% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202574 flights81.1%
Oct–Dec 202591 flights71.4%
Jan–Mar 202690 flights78.7%

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

By weekday, DL 883 did best on Wednesday at 84.8% on time and worst on Saturday at 68.1%. Each day rests on about 49 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 883 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 4,643 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.

Extreme weather

The largest share of delay minutes, 49%, 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 2,267 of the 4,643 delay minutes reported here. The split is drawn from 4,643 delay minutes reported on DL 883.

Cancellations are rare at 0.29%, 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

6.4% 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 1,979 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 346 flights under DL 883 in the data flew DTW to LAX. 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. 346 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 883
