These figures cover 275 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:25 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 693 runs 3 points worse at 81.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 693 quarter by quarter
DL 693 did not run the same all year. Its best quarter was Jul–Sep 2026 at 95.1% on time and its weakest Oct–Dec 2025 at 72.7%, a swing of 22 points on roughly 69 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 202589 flights72.7%
- Jan–Mar 202627 flights—
- Apr–Jun 202667 flights80.3%
- Jul–Sep 202662 flights95.1%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 693 did best on Wednesday at 89.2% on time and worst on Monday at 74.4%. Each day rests on about 39 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Share of 272 completed flights by arrival against schedule.
9 of 39 late departures made up the time and arrived on time, 23% of them. In the other direction, 21 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 SFO.
The worst days
Worst days for DL 693
The latest arrival of the period was on 16 March 2026, 3 hours 25 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 3 hours 25 minutes | Carrier |
| 18 September 2025 | 2 hours 56 minutes | Carrier |
| 29 November 2025 | 2 hours 50 minutes | Carrier |

Delay causes
Why DL 693 runs late
Carrier accounts for 53% of the 2,693 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 36%National Airspace System
- 9%Late-arriving aircraft
- 2%Extreme weather
36% 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 958 minutes out of 2,693, against a national NAS share of 21%. The split is drawn from 2,693 delay minutes reported on DL 693.
Cancellations are rare at 0.73%, 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
5.5% 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 55 minutes, which a normal layover absorbs.
At 2,139 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 three other city pairs in the data, including SFO to ATL (152), DTW to ROC (61) and ATL to CMH (24), but none flew often enough under DL 693 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to SFO only.
One caution: this is a thin sample. 275 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.
