Historical statistics for July 2025 to June 2026, not live status. For today’s DL 858, check with Delta Air Lines.

DL 858 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 311 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 858's record is 6 points better than the US average of 77.6%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 311 flights between July 2025 and June 2026. The median arrival is 9 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 858 flies

DL 858 flies LAX to BNA without a single fixed slot. Its most common scheduled departure was 15:00, used on 53 of 311 flights, with 17:59 (50 flights) and 18:10 (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 15:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 858 runs 11 points better at 83.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 858 quarter by quarter

Quarter by quarter DL 858 held fairly steady: 87.9% in Jul–Sep 2025, 80.4% in Oct–Dec 2025, 84.0% in Jan–Mar 2026 and 80.7% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202591 flights87.9%
Oct–Dec 202546 flights80.4%
Jan–Mar 202686 flights84.0%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 858 did best on Thursday at 89.4% on time and worst on Sunday at 74.4%. Each day rests on about 44 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 858 runs late

One category carries most of the weight here. Carrier accounts for 74% of the 3,606 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.

Carrier
74%
Late-arriving aircraft
14%
National Airspace System
11%

The largest share of delay minutes, 74%, 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 2,685 of the 3,606 delay minutes reported here. The split is drawn from 3,606 delay minutes reported on DL 858.

Cancellations sit at 1.61% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 1,798 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.

The same number turns up on one other city pair in the data, including MSP to SFO (16), but none flew often enough under DL 858 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to BNA only.

One caution: this is a thin sample. 311 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 858
