These figures cover 250 flights between September 2025 and August 2026. The median arrival is 9 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 AS 710 flies

AS 710 is scheduled to leave Spokane (GEG) at 05:00 local time and reach Portland (PDX) at 06:10. That slot held for 225 of the 250 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 05:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 710 runs 7 points better at 96.4%. 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 7 August 2026, 12 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).

Delay causes

Why AS 710 runs late

Late-arriving aircraft accounts for 50% of the 1,475 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
50%
Carrier
45%
National Airspace System
4%

50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,475 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 1,475 delay minutes reported on AS 710.

Cancellations are rare at 0.40%, 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 1.6% 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.

The same number turns up on one other city pair in the data, including BOI to SEA (1), but none flew often enough under AS 710 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GEG to PDX only.

One caution: this is a thin sample. 250 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 710

For a booking, AS 710 has one of the better records a US domestic flight can show: 96.4% on time and 0.40% cancelled. That is a base rate, not a promise about any single day.
