This route lands a B, 4 points better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 1,928 JAX to CLT flights, with a median arrival 9 minutes early.
Best time to fly JAX to CLT: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 91.5% of the time and Wednesday flights 89.7%, against 81.7% for the route overall.
Set against the rest of the country, this route's record is 4 points better than the US average of 77.3%. That gap is worth roughly 44 fewer late arrivals for every thousand flights.

These figures cover 1,928 flights between September 2025 and August 2026. The median arrival is 9 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.

Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against half a point between the best and worst carrier.

- 8am–11am292 flights90.4%

Scale runs 60% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.5% of the time, against 66.3% for the overnight window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 421 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 20 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
July is the worst month at 69.5% on time, 20 points below October, the best at 89.8%. 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. March was the busiest month here, with 180 flights.
Across the week, Wednesday is the strongest day at 89.7% on time and Sunday the weakest at 74.6%, a spread of 15 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 57% of the 30,000 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 32%Carrier
- 7%National Airspace System
- 4%Extreme weather
- 0%Security
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 30,000 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 30,227 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.5% on time here.
Cancellations sit at 1.04% against a national 1.89%, which is ordinary. Diversions add another 0.21%.
Connections and stage length
What a delay here actually costs
7.0% 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 an hour and a half, which a normal layover absorbs.
At 328 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 77.2% on time across 1,929 flights, 5 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 5 points of difference.
The sample behind these figures is 1,928 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 this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 89.8% on time and July 69.5%, a swing of 20 points. If the dates move at all, move them out of July before you think about anything else. 1,904 completed flights over 12 months sit behind that.
Common questions
JAX to CLT questions
How often is JAX to CLT delayed?
Roughly one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.3% of the 1,928 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is JAX to CLT compared with the rest of the country?
81.7% of flights arrive on time here against a national 77.3%, a difference of 4 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on JAX to CLT?
The 5am–8am departure window is the strongest at 91.5% on time. The 8pm–5am window is the weakest at 66.3%, 25 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on JAX to CLT?
July is the weakest month at 69.5% on time, compared with 89.8% in October. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
