Across the year
DL 714 quarter by quarter
DL 714 did not run the same all year. Its best quarter was Oct–Dec 2025 at 76.2% on time and its weakest Jul–Sep 2026 at 49.2%, a swing of 27 points on roughly 78 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.

Scale runs 40% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, DL 714 did best on Saturday at 76.7% on time and worst on Wednesday at 54.5%. Each day rests on about 44 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Share of 309 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 73 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 42 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 SEA.
The worst days
Worst days for DL 714
The latest arrival of the period was on 22 February 2026, 13 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across February, June and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 February 2026 | 13 hours 23 minutes | Carrier |
| 26 June 2026 | 12 hours 31 minutes | Carrier |
| 18 June 2026 | 4 hours 37 minutes | Extreme weather |
| 19 July 2026 | 4 hours 29 minutes | Late-arriving aircraft |
| 10 July 2026 | 4 hours 20 minutes | Late-arriving aircraft |
Delay causes
Why DL 714 runs late
Carrier accounts for 58% of the 7,830 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 22%National Airspace System
- 15%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,518 of the 7,830 delay minutes reported here. The split is drawn from 7,830 delay minutes reported on DL 714.
Cancellations are rare at 0.32%, 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
10.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 2,182 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 one other city pair in the data, including SEA to CVG (16), but none flew often enough under DL 714 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to SEA only.
One caution: this is a thin sample. 310 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 714
