DL 458 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.3%. When something does go wrong the average delay runs roughly 30 minutes. That rests on 336 flights, with a median arrival 6 minutes early.

These figures cover 336 flights between September 2025 and August 2026. The median arrival is 6 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.

Delay causes

Why DL 458 runs late

Late-arriving aircraft accounts for 51% of the 1,635 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
51%
Carrier
34%
National Airspace System
16%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,635 reported delay minutes here, that single category outweighs weather by 51 to one. The split is drawn from 1,635 delay minutes reported on DL 458.

Cancellations sit at 1.79% against a national 1.89%, 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 0.6% land an hour or more behind schedule, against 8.3% 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.

Every one of the 336 flights under DL 458 in the data flew LAX to CVG. 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. 336 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
