Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Delta Air Lines.

Delta on CLT to ATL earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 2,611 flights, with a median arrival 14 minutes early.

Set against the rest of the country, Delta's CLT to ATL record is 10 points better than the US average of 77.6%. That gap is worth roughly 96 fewer late arrivals for every thousand flights.

These figures cover 2,611 flights between July 2025 and June 2026. The median arrival is 14 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.

Carrier by carrier

Delta against every carrier on CLT to ATL

Delta flew 2,611 of the 4,409 flights on CLT to ATL, most of the route. Its 87.2% on time is 4 points better than the route as a whole, which runs 83.3%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Delta at 87.2% to American at 70.5%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Delta runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am671 flights93.3%
8am–11am640 flights91.3%
11am–2pm359 flights87.2%
2pm–5pm404 flights82.6%
5pm–8pm497 flights78.9%
8pm–5am40 flights72.5%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.3% of the time, against 72.5% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 671 flights scheduled in it.

Across the year

Delta on CLT to ATL through the year

Darker means more delays. Figures are on-time percentages.September best, July worst

July is the worst month at 81.0% on time, 11 points below September, the best at 92.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 251 flights.

Across the week, Wednesday is the strongest day at 93.2% on time and Sunday the weakest at 80.1%. 13 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Delta runs late on this route

One category carries most of the weight here. Carrier accounts for 42% of the 26,000 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.

42%
Late-arriving aircraft
36%
National Airspace System
18%
Extreme weather
4%

36% 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 26,000 reported delay minutes here, that single category outweighs weather by 10 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 26,264 reported delay minutes.

The largest share of delay minutes, 42%, 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 11,000 of the 26,000 delay minutes reported here.

Cancellations sit at 1.34% against a national 1.81%, which is ordinary. Diversions add another 0.11%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 226 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.3% on time across 2,610 flights, 6 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.

The sample behind these figures is 2,611 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking Delta on CLT to ATL

Put together: avoid the 8pm–5am departure. It runs 72.5% on time against 93.3% for the 5am–8am slot, and that 21 points is the largest single thing you control here. PSA Airlines is the strongest operator if the fares are close. 2,573 completed flights over 12 months sit behind that.
