This route 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 11 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 1,166 HHH to CLT flights, with a median arrival 16 minutes early.
Best time to fly HHH to CLT: a 11am–2pm departure, ideally on a Tuesday. Flights in that window arrived on time 94.7% of the time and Tuesday flights 92.4%, against 88.5% for the route overall.
Set against the rest of the country, this route's record is 11 points better than the US average of 77.3%. That gap is worth roughly 112 fewer late arrivals for every thousand flights.

These figures cover 1,166 flights between September 2025 and August 2026. The median arrival is 16 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.

The most reliable ways to fly Hilton Head Island to Charlotte
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 2 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. HHH → CLTHilton Head Island to Charlotte | Envoy Air | 87.1% | 88.5% | 1.63% | 11am–2pm, Tue | — |

| 3. SAV → CLTSavannah to Charlotte | PSA Airlines | 83.8% | 85.9% | 2.40% | 5am–8am, Wed | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
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 10 points, against half a point between the best and worst carrier.

The best window here is not the first bank but the 11am–2pm slot at 94.7% on time, ahead of 5pm–8pm at 84.5%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 442 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 12 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.
August is the worst month at 83.2% on time, 12 points below September, the best at 95.6%. 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. May was the busiest month here, with 136 flights.
Across the week, Tuesday is the strongest day at 92.4% on time and Saturday the weakest at 83.3%, a spread of 9 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 63% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 23%Carrier
- 8%Extreme weather
- 6%National Airspace System
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 12,899 reported delay minutes.
Cancellations sit at 1.63% against a national 1.89%, which is ordinary. Diversions add another 0.09%.
Connections and stage length
What a delay here actually costs
5.3% 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 206 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 85.5% on time across 1,166 flights, 3 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 3 points of difference.
The sample behind these figures is 1,166 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. September runs 95.6% on time and August 83.2%, a swing of 12 points. If the dates move at all, move them out of August before you think about anything else. 1,146 completed flights over 12 months sit behind that.
Common questions
HHH to CLT questions

How reliable is HHH to CLT compared with the rest of the country?
88.5% of flights arrive on time here against a national 77.3%, a difference of 11 points in its favour. That is worth a A on this site's grading scale.
What time of day has the fewest delays on HHH to CLT?
The 11am–2pm departure window is the strongest at 94.7% on time. The 5pm–8pm window is the weakest at 84.5%, 10 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 August delays on HHH to CLT?
August is the weakest month at 83.2% on time, compared with 95.6% in September. Across the year that is 12 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
