These figures cover 271 flights between September 2025 and August 2026. The median arrival is 9 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 613 quarter by quarter
AS 613 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.9% on time and its weakest Jul–Sep 2026 at 24.2%, a swing of 67 points on roughly 68 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 613 did best on Tuesday at 84.4% on time and worst on Thursday at 61.4%. Each day rests on about 39 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

The worst days

The latest arrival of the period was on 10 August 2026, 5 hours 7 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across August, May, February, December and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 August 2026 | 5 hours 7 minutes | Late-arriving aircraft |
| 28 May 2026 | 4 hours 17 minutes | National Airspace System |
| 12 February 2026 | 3 hours 50 minutes | Carrier |

Delay causes
Why AS 613 runs late
National Airspace System accounts for 64% of the 4,202 delay minutes carriers reported here, and the remaining four split what is left.
- 64%National Airspace System
- 19%Late-arriving aircraft
- 16%Carrier
- 1%Extreme weather
64% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,687 minutes out of 4,202, against a national NAS share of 21%. The split is drawn from 4,202 delay minutes reported on AS 613.
Cancellations are rare at 0.74%, 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
7.8% 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 about an hour, which a normal layover absorbs.
Every one of the 271 flights under AS 613 in the data flew LAS to SFO. 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. 271 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.
