Historical statistics for July 2025 to June 2026, not live status. For today’s DL 714, check with Delta Air Lines.
DL 714 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 299 flights, with a median arrival right on schedule.
The national on-time rate over the same period is 77.6%, so DL 714 runs 9 points behind the country as a whole. Across a thousand flights that is about 86 extra late arrivals.

These figures cover 299 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Schedule
When DL 714 flies
DL 714 flies ATL to SEA without a single fixed slot. Its most common scheduled departure was 18:20, used on 68 of 299 flights, with 18:00 (48 flights) and 18:17 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 18:2068 flights22.7%

- Departs 18:1735 flights11.7%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 18:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 714 runs level with that at 69.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 714 quarter by quarter
DL 714 did not run the same all year. Its best quarter was Jul–Sep 2025 at 77.5% on time and its weakest Apr–Jun 2026 at 57.4%, a swing of 20 points on roughly 75 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.
- Jul–Sep 202572 flights77.5%
- Oct–Dec 202580 flights76.2%
- Jan–Mar 202686 flights63.5%
- Apr–Jun 202661 flights57.4%
Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 714 did best on Saturday at 81.1% on time and worst on Friday at 54.8%. Each day rests on about 43 flights, so a gap of 26 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 714 runs late
One category carries most of the weight here. Carrier accounts for 57% of the 5,704 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 57%Carrier
- 27%National Airspace System
- 9%Late-arriving aircraft
- 7%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,231 of the 5,704 delay minutes reported here. The split is drawn from 5,704 delay minutes reported on DL 714.
Cancellations are rare at 0.33%, below the national 1.81% 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
7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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. 299 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
