These figures cover 339 flights between September 2025 and August 2026. The median arrival is 5 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 09:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AS 216 runs 5 points worse at 78.9%. 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 worst days
Worst days for AS 216
The latest arrival of the period was on 13 March 2026, 7 hours 54 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 7 hours 54 minutes | Late-arriving aircraft |
| 6 August 2026 | 6 hours 47 minutes | Carrier |
| 30 September 2025 | 2 hours 13 minutes | Late-arriving aircraft |
| 19 May 2026 | 2 hours 5 minutes | Carrier |
| 20 December 2025 | 1 hour 41 minutes | Late-arriving aircraft |
Delay causes
Why AS 216 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 3,653 reported delay minutes.
- 42%Carrier
- 41%Late-arriving aircraft
- 17%National Airspace System
- 0%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,653 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 3,653 delay minutes reported on AS 216.
Cancellations are rare at 0.88%, 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 4.8% 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 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 (276 flights, 58.1% 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.
