DL 3117 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 3117's record is 8 points better than the US average of 77.6%. That gap is worth roughly 77 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 10 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.

Schedule

When DL 3117 flies

DL 3117 flies ATL to JAN without a single fixed slot. Its most common scheduled departure was 23:00, used on 92 of 365 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 23:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 3117 runs 15 points better at 85.3%. 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 3117 quarter by quarter

Quarter by quarter DL 3117 held fairly steady: 86.8% in Jul–Sep 2025, 84.4% in Oct–Dec 2025, 80.9% in Jan–Mar 2026 and 88.9% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights86.8%
Oct–Dec 202592 flights84.4%
Jan–Mar 202690 flights80.9%
Apr–Jun 202691 flights88.9%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3117 did best on Wednesday at 96.2% on time and worst on Thursday at 76.5%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3117 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,235 reported delay minutes.

Late-arriving aircraft
39%
Carrier
39%
National Airspace System
14%
Extreme weather
8%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,235 reported delay minutes here, that single category outweighs weather by 5 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,235 delay minutes reported on DL 3117.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.1% 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.

Every one of the 365 flights under DL 3117 in the data flew ATL to JAN. 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. 365 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 3117

For a booking, DL 3117 has one of the better records a US domestic flight can show: 85.3% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
