Historical statistics for July 2025 to June 2026, not live status. For today’s DL 466, check with Delta Air Lines.

DL 466 lands a B+, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 305 flights, with a median arrival 2 minutes early.

These figures cover 305 flights between July 2025 and June 2026. The median arrival is 2 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 466 flies

DL 466 flies ATL to LAS without a single fixed slot. Its most common scheduled departure was 11:00, used on 134 of 305 flights, with 11:05 (54 flights) and 10:39 (35 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 11:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 466 runs level with that at 78.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 466 quarter by quarter

Quarter by quarter DL 466 held fairly steady: 83.5% in Jul–Sep 2025, 76.9% in Oct–Dec 2025, 74.4% in Jan–Mar 2026 and 80.6% 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.

By weekday, DL 466 did best on Thursday at 90.7% on time and worst on Saturday at 65.9%. Each day rests on about 44 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 466 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 2,806 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.

National Airspace System

Extreme weather

The largest share of delay minutes, 62%, 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 1,729 of the 2,806 delay minutes reported here. The split is drawn from 2,806 delay minutes reported on DL 466.

Cancellations are rare at 0.33%, 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

Badly late arrivals are rare here: only 4.9% 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 1,747 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.

DL 466 is not only a ATL to LAS flight. It also flew LAS to ATL (291 flights, 85.1% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 305 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.
