Historical statistics for July 2025 to June 2026, not live status. For today’s AS 216, check with Alaska Airlines.
AS 216 lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 339 flights, with a median arrival 2 minutes early.

These figures cover 339 flights between July 2025 and June 2026. The median arrival is 2 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 216 flies
AS 216 flies SEA to CLE without a single fixed slot. Its most common scheduled departure was 10:37, used on 50 of 339 flights, with 10:17 (44 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:37 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 216 runs 8 points worse at 76.4%. 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
AS 216 quarter by quarter
AS 216 did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.7% on time and its weakest Jul–Sep 2025 at 65.9%, a swing of 24 points on roughly 85 flights a quarter. 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.

By weekday, AS 216 did best on Thursday at 84.3% on time and worst on Friday at 68.0%. Each day rests on about 48 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 216 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 3,434 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.
- 46%Late-arriving aircraft
- 36%Carrier
- 18%National Airspace System
- 0%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,434 reported delay minutes here, that single category outweighs weather by 46 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,434 delay minutes reported on AS 216.
Cancellations sit at 1.18% against a national 1.81%, 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 4.2% 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 2,021 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.
AS 216 is not only a SEA to CLE flight. It also flew CLE to SEA (274 flights, 57.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 339 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.
