AS 24 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 11 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 12 minutes early.
Set against the rest of the country, AS 24's record is 11 points better than the US average of 77.3%. That gap is worth roughly 112 fewer late arrivals for every thousand flights.

These figures cover 365 flights between September 2025 and August 2026. The median arrival is 12 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 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 24 runs level with that at 88.5%. 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 24 quarter by quarter
Quarter by quarter AS 24 held fairly steady: 85.4% in Oct–Dec 2025, 88.2% in Jan–Mar 2026, 89.9% in Apr–Jun 2026 and 87.3% in Jul–Sep 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202690 flights88.2%
- Apr–Jun 202691 flights89.9%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 24 ranged from 82.6% on Sunday to 94.1% on Thursday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.
Arrival by arrival
How late AS 24 runs when it is late
AS 24 often beats the schedule: 160 of 347 completed flights, 46%, arrived 15 minutes or more early. Most of the lateness is short. 26 of the 40 late arrivals were under half an hour behind, and 8 reached an hour or more.

Share of 347 completed flights by arrival against schedule.
A late pushback is often recovered here: of 23 departures that left 15 minutes late or more, 9 still arrived on time. In the other direction, 26 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 JFK.
The worst days
Worst days for AS 24
The latest arrival of the period was on 14 December 2025, 5 hours 54 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 5 hours 54 minutes | National Airspace System |
| 24 February 2026 | 5 hours 27 minutes | Extreme weather |
| 30 November 2025 | 4 hours 17 minutes | Carrier |
| 7 August 2026 | 3 hours 41 minutes | National Airspace System |
| 9 November 2025 | 1 hour 47 minutes | National Airspace System |
Delay causes
Why AS 24 runs late
National Airspace System accounts for 66% of the 2,299 delay minutes carriers reported here, and the remaining four split what is left.
- 66%National Airspace System
- 18%Extreme weather
- 15%Carrier
Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.1 times the usual weather exposure. The split is drawn from 2,299 delay minutes reported on AS 24.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 3.01%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.3% 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 2,446 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 365 flights under AS 24 in the data flew SAN to JFK. 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. 365 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 24
