DL 470 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 361 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 470's record is 12 points better than the US average of 77.6%. That gap is worth roughly 118 fewer late arrivals for every thousand flights.

These figures cover 361 flights between July 2025 and June 2026. The median arrival is 12 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 470 flies

DL 470 flies LAS to DTW without a single fixed slot. Its most common scheduled departure was 09:59, used on 87 of 361 flights, with 09:55 (65 flights) and 09:58 (63 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 09:59 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 470 runs 5 points better at 89.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 470 quarter by quarter

Quarter by quarter DL 470 held fairly steady: 86.7% in Jul–Sep 2025, 89.9% in Oct–Dec 2025, 87.8% in Jan–Mar 2026 and 93.3% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 470 ranged from 84.6% on Wednesday to 96.2% on Tuesday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 470 runs late

One category carries most of the weight here. Carrier accounts for 52% of the 1,978 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.

Carrier
52%
Late-arriving aircraft
31%
National Airspace System
18%

The largest share of delay minutes, 52%, 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 1,022 of the 1,978 delay minutes reported here. The split is drawn from 1,978 delay minutes reported on DL 470.

Cancellations are rare at 0.28%, 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 3.1% 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 1,749 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 361 flights under DL 470 in the data flew LAS to DTW. 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. 361 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 470

For a booking, DL 470 has one of the better records a US domestic flight can show: 89.4% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
