These figures cover 306 flights between September 2025 and August 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.

Across the year
DL 466 quarter by quarter
DL 466 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Jan–Mar 2026 at 74.4%, a swing of 16 points on roughly 61 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Scale runs 65% to 95%.
By weekday, DL 466 did best on Wednesday at 88.4% on time and worst on Tuesday at 72.7%. Each day rests on about 44 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 304 completed flights by arrival against schedule.
9 of 49 late departures made up the time and arrived on time, 18% of them. In the other direction, 23 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LAS.
The worst days
Worst days for DL 466
The latest arrival of the period was on 26 June 2026, 3 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 June 2026 | 3 hours 23 minutes | Carrier |
| 8 June 2026 | 2 hours 30 minutes | Carrier |
| 25 October 2025 | 2 hours 24 minutes | Carrier |

Delay causes
Why DL 466 runs late
Carrier accounts for 59% of the 2,588 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 29%National Airspace System
- 12%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,528 of the 2,588 delay minutes reported here. The split is drawn from 2,588 delay minutes reported on DL 466.
Cancellations are rare at 0.65%, below the national 1.89% 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 3.6% 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 1,747 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 (292 flights, 81.7% 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. 306 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.
