DL 800 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 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 348 flights, with a median arrival 9 minutes early.

These figures cover 348 flights between September 2025 and August 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.

A 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 800 runs 3 points worse at 86.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why DL 800 runs late

Late-arriving aircraft accounts for 47% of the 4,351 delay minutes carriers reported here, and the remaining four split what is left.

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,351 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 4,351 delay minutes reported on DL 800.

Cancellations sit at 1.72% against a national 1.89%, which is ordinary. Diversions add another 0.57%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.7% 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 2,343 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 348 flights under DL 800 in the data flew FLL 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. 348 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 800
