Across the year
AS 19 quarter by quarter
AS 19 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.7% on time and its weakest Oct–Dec 2025 at 57.3%, a swing of 29 points on roughly 91 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 19 did best on Saturday at 79.6% on time and worst on Thursday at 62.7%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Share of 354 completed flights by arrival against schedule.
16 of 65 late departures made up the time and arrived on time, 25% of them. In the other direction, 46 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 PDX.
The worst days
Worst days for AS 19
The latest arrival of the period was on 29 August 2026, 7 hours 31 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 |
|---|---|---|
| 29 August 2026 | 7 hours 31 minutes | Late-arriving aircraft |
| 24 February 2026 | 5 hours 33 minutes | Late-arriving aircraft |
| 18 March 2026 | 5 hours 28 minutes | Carrier |
| 14 December 2025 | 5 hours 11 minutes | Late-arriving aircraft |
| 19 October 2025 | 4 hours 55 minutes | Carrier |
Delay causes
Why AS 19 runs late
Late-arriving aircraft accounts for 42% of the 6,800 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 34%National Airspace System
- 14%Carrier
- 5%Extreme weather
- 5%Security
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,800 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 6,800 delay minutes reported on AS 19.
Cancellations sit at 1.93% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
8.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
At 2,454 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.
Every one of the 362 flights under AS 19 in the data flew JFK to PDX. 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. 362 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 19
For a booking, read AS 19 as 73.2% on time with 1.93% cancelled over 362 flights. Those are rates from the past twelve months, not a forecast for any particular day.
