Historical statistics for July 2025 to June 2026, not live status. For today’s DL 458, check with Delta Air Lines.

DL 458 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 35 minutes. That rests on 337 flights, with a median arrival 7 minutes early.

Set against the rest of the country, DL 458's record is 8 points better than the US average of 77.6%. That gap is worth roughly 79 fewer late arrivals for every thousand flights.

These figures cover 337 flights between July 2025 and June 2026. The median arrival is 7 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 458 flies

DL 458 flies LAX to CVG without a single fixed slot. Its most common scheduled departure was 22:00, used on 96 of 337 flights, with 22:55 (49 flights) and 22:13 (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 22:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 458 runs 15 points better at 85.5%. 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 458 next to LAX to CVG

Across the year

DL 458 quarter by quarter

Quarter by quarter DL 458 held fairly steady: 89.6% in Jul–Sep 2025, 87.3% in Oct–Dec 2025, 80.5% in Jan–Mar 2026 and 85.1% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202579 flights89.6%
Oct–Dec 202580 flights87.3%
Jan–Mar 202690 flights80.5%

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

By weekday, DL 458 did best on Tuesday at 92.5% on time and worst on Sunday at 74.0%. Each day rests on about 48 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 458 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 1,685 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.

Late-arriving aircraft
51%
Carrier
37%
National Airspace System
12%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,685 reported delay minutes here, that single category outweighs weather by 51 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,685 delay minutes reported on DL 458.

Cancellations sit at 2.08% 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 1.2% 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 1,900 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 two other city pairs in the data, including HSV to ATL (5) and ATL to HSV (5), but none flew often enough under DL 458 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to CVG only.

One caution: this is a thin sample. 337 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 458

For a booking, read DL 458 as 85.5% on time with 2.08% cancelled over 337 flights. Those are rates from the past twelve months, not a forecast for any particular day.
