This route 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 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 1,187 SGF to CLT flights, of which Envoy Air flew 568 at 91.4% on time.
Best time to fly SGF to CLT: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 94.9% of the time and Tuesday flights 91.7%, against 86.1% for the route overall.
Set against the rest of the country, this route's record is 9 points better than the US average of 77.6%. That gap is worth roughly 85 fewer late arrivals for every thousand flights.

These figures cover 1,187 flights between July 2025 and June 2026. The median arrival is 11 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
Which airline is most reliable on SGF to CLT
The choice of carrier is not cosmetic here. Envoy Air arrives on time 91.4% of the time; PSA Airlines manages 81.1%. Sample sizes sit next to every figure, because a two-point gap across 619 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air | 568 | 91.4% | 62 min | 1.41% | A |
| PSA Airlines | 619 | 81.1% | 115 min | 2.42% | B |
Envoy leads PSA by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Best ways to make this trip
The most reliable ways to fly Springfield to Charlotte
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. SGF → CLTSpringfield to Charlotte | Envoy Air | 90.1% | 91.4% | 1.41% | 8am–11am, Tue | MQ 4083 06:15 |
| 2. SGF → CLTSpringfield to Charlotte | PSA Airlines | 79.1% | 81.1% | 2.42% | 11am–2pm, 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 20 points, against 10 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am296 flights94.2%
- 8am–11am83 flights94.9%
- 11am–2pm430 flights85.3%
- 2pm–5pm150 flights83.9%
- 5pm–8pm228 flights75.1%
- 8pm–5am—
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 94.9% of the time, against 75.1% for the evening window. That is 20 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 430 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 17 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.
June is the worst month at 78.6% on time, 17 points below January, the best at 96.0%. 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. August was the busiest month here, with 115 flights.
Across the week, Tuesday is the strongest day at 91.7% on time and Saturday the weakest at 81.9%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Late-arriving aircraft accounts for 42% of the 16,000 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
- 33%Carrier
- 17%Extreme weather
- 8%National Airspace System
- 0%Security
Extreme weather accounts for 17% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 16,054 reported delay minutes.
42% 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 16,000 reported delay minutes here, that single category outweighs weather by 3 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.
Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.17%.
Connections and stage length
What a delay here actually costs
5.7% 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 an hour and a half, which a normal layover absorbs.
The 708 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 81.9% on time across 1,187 flights, 4 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 4 points of difference.
The sample behind these figures is 1,187 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. January runs 96.0% on time and June 78.6%, a swing of 17 points. If the dates move at all, move them out of June before you think about anything else. 1,162 completed flights over 12 months sit behind that.
Common questions
SGF to CLT questions
How often is SGF to CLT delayed?
About one flight in seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.9% of the 1,187 flights in this analysis, against 22.4% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on SGF to CLT?
Envoy Air leads at 91.4% on time across 568 flights. PSA Airlines is at the other end on 81.1%, a gap of 10 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on SGF to CLT?
The 8am–11am departure window is the strongest at 94.9% on time. The 5pm–8pm window is the weakest at 75.1%, 20 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 June delays on SGF to CLT?
June is the weakest month at 78.6% on time, compared with 96.0% in January. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
