These figures cover 334 flights between September 2025 and August 2026. The median arrival is 6 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 753 quarter by quarter

By weekday, DL 753 did best on Thursday at 87.5% on time and worst on Friday at 72.9%. Each day rests on about 48 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival

Share of 330 completed flights by arrival against schedule.
17 of 57 late departures made up the time and arrived on time, 30% of them. In the other direction, 18 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 LAX.

Delay causes

- 54%Carrier
- 25%National Airspace System
- 16%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,534 of the 2,864 delay minutes reported here. The split is drawn from 2,864 delay minutes reported on DL 753.
Cancellations sit at 0.90% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
5.8% 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 50 minutes, which a normal layover absorbs.
At 1,947 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 334 flights under DL 753 in the data flew ATL to LAX. 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. 334 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
