These figures cover 362 flights between September 2025 and August 2026. The median arrival is 11 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 09:59 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 470 runs 6 points better at 90.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

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.

The latest arrival of the period was on 22 August 2026, 9 hours 33 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 August 2026 | 9 hours 33 minutes | Carrier |
| 29 October 2025 | 4 hours 12 minutes | Carrier |

Delay causes
Why DL 470 runs late
Carrier accounts for 55% of the 2,082 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 32%Late-arriving aircraft
- 13%National Airspace System
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,135 of the 2,082 delay minutes reported here. The split is drawn from 2,082 delay minutes reported on DL 470.
Cancellations are rare at 0.28%, 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 2.5% 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 1,749 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 362 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. 362 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: 90.0% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
