AS 705 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 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about 50 minutes. That rests on 266 flights, with a median arrival 8 minutes early.
Set against the rest of the country, AS 705's record is 10 points better than the US average of 77.3%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 266 flights between September 2025 and August 2026. The median arrival is 8 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 705 flies
AS 705 flies OAK to SEA without a single fixed slot. Its most common scheduled departure was 07:00, used on 63 of 266 flights, with 10:22 (60 flights) and 06:15 (43 flights) next.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 705 runs 2 points worse at 87.3%. 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
AS 705 quarter by quarter
Quarter by quarter AS 705 held fairly steady: 86.2% in Jan–Mar 2026, 90.0% in Apr–Jun 2026 and 86.4% in Jul–Sep 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202690 flights86.2%
- Apr–Jun 202691 flights90.0%
- Jul–Sep 202660 flights86.4%
Scale runs 80% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 705 did best on Saturday at 94.4% on time and worst on Friday at 79.5%. Each day rests on about 38 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 705 runs when it is late
AS 705 often beats the schedule: 73 of 260 completed flights, 28%, arrived 15 minutes or more early. Most of the lateness is short. 17 of the 33 late arrivals were under half an hour behind, and 5 reached an hour or more.

Scale runs 0% to 100%.
Share of 260 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 21 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 13 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 SEA.
The worst days
Worst days for AS 705
The latest arrival of the period was on 27 March 2026, 7 hours 42 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, June, July and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 March 2026 | 7 hours 42 minutes | Carrier |
| 21 June 2026 | 2 hours 22 minutes | Late-arriving aircraft |
| 23 June 2026 | 1 hour 48 minutes | Late-arriving aircraft |

Delay causes
Why AS 705 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,645 reported delay minutes.
- 40%Carrier
- 38%National Airspace System
- 22%Late-arriving aircraft
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 664 of the 1,645 delay minutes reported here. The split is drawn from 1,645 delay minutes reported on AS 705.
Cancellations sit at 2.26% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.9% 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 672 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.
The same number turns up on one other city pair in the data, including SFO to LAS (38), but none flew often enough under AS 705 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OAK to SEA only.
One caution: this is a thin sample. 266 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 705
For a booking, read AS 705 as 87.3% on time with 2.26% cancelled over 266 flights. Those are rates from the past twelve months, not a forecast for any particular day.
