These figures cover 361 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.

Across the year
DL 1465 quarter by quarter

Share of 355 completed flights by arrival against schedule.
23 of 84 late departures made up the time and arrived on time, 27% of them. In the other direction, 19 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 SAT.

Delay causes
Why DL 1465 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 3,883 reported delay minutes.
- 39%Carrier
- 31%Late-arriving aircraft
- 26%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,507 of the 3,883 delay minutes reported here. The split is drawn from 3,883 delay minutes reported on DL 1465.
Cancellations sit at 1.66% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.9% 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 roughly 50 minutes, which a normal layover absorbs.
The 874 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on two other city pairs in the data, including SAT to ATL (228) and ATL to LAX (1), but none flew often enough under DL 1465 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to SAT only.
One caution: this is a thin sample. 361 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 DL 1465
For a booking, read DL 1465 as 77.5% on time with 1.66% cancelled over 361 flights. Those are rates from the past twelve months, not a forecast for any particular day.
