These figures cover 271 flights between September 2025 and August 2026. The median arrival is 10 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 701 runs 6 points better at 95.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

The latest arrival of the period was on 3 January 2026, 2 hours 2 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 January 2026 | 2 hours 2 minutes | Carrier |
| 9 January 2026 | 2 hours 1 minute | Carrier |
| 24 August 2026 | 1 hour 43 minutes | National Airspace System |

Delay causes
Why AS 701 runs late
Carrier accounts for 54% of the 631 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 45%National Airspace System
- 1%Security
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 340 of the 631 delay minutes reported here. The split is drawn from 631 delay minutes reported on AS 701.
Cancellations are rare at 0.74%, 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 1.1% 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.
The 867 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 271 flights under AS 701 in the data flew LAS to SEA. 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. 271 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 AS 701
For a booking, AS 701 has one of the better records a US domestic flight can show: 95.5% on time and 0.74% cancelled. That is a base rate, not a promise about any single day.
