These figures cover 341 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.

A 07:35 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 946 runs level with that at 87.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

- 86%Carrier
- 13%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 86%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,676 of the 4,258 delay minutes reported here. The split is drawn from 4,258 delay minutes reported on DL 946.
Cancellations sit at 2.35% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.0% 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 close to two hours, which a normal layover absorbs.
The 1,242 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 AUS to LAX (177) and RSW to DTW (24), but none flew often enough under DL 946 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to AUS only.
One caution: this is a thin sample. 341 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 946
