These figures cover 277 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.

Across the year
AS 432 quarter by quarter
AS 432 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.0% on time and its weakest Jan–Mar 2026 at 72.7%, a swing of 14 points on roughly 92 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.

- Oct–Dec 202590 flights85.6%
- Jan–Mar 202688 flights72.7%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 432 did best on Saturday at 90.0% on time and worst on Tuesday at 75.6%. Each day rests on about 40 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 432 runs when it is late
AS 432 often beats the schedule: 99 of 276 completed flights, 36%, arrived 15 minutes or more early. The 50 late arrivals split 20 under half an hour, 10 between 30 and 60 minutes, and 20 an hour or more.

Share of 276 completed flights by arrival against schedule.
13 of 49 late departures made up the time and arrived on time, 27% of them. In the other direction, 14 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 TPA.
The worst days
Worst days for AS 432
The latest arrival of the period was on 17 April 2026, 7 hours 5 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 April 2026 | 7 hours 5 minutes | Late-arriving aircraft |
| 22 December 2025 | 5 hours 2 minutes | Late-arriving aircraft |
| 30 January 2026 | 3 hours 51 minutes | Late-arriving aircraft |
| 27 January 2026 | 2 hours 56 minutes | Late-arriving aircraft |
| 2 October 2025 | 2 hours 23 minutes | Carrier |
Delay causes
Why AS 432 runs late
Late-arriving aircraft accounts for 55% of the 3,571 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 26%Carrier
- 12%National Airspace System
- 7%Extreme weather
- 0%Security
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,571 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 3,571 delay minutes reported on AS 432.
Cancellations are rare at 0.36%, 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
7.2% 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 2,087 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.
The same number turns up on one other city pair in the data, including DEN to ANC (70), but none flew often enough under AS 432 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAN to TPA only.
One caution: this is a thin sample. 277 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 432
For a booking, read AS 432 as 81.9% on time with 0.36% cancelled over 277 flights. Those are rates from the past twelve months, not a forecast for any particular day.
