Every carrier on DFW to CHS, 1,247 flights

These figures cover 171 flights between July 2025 and June 2026. The median arrival is 12 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

Envoy against every carrier on DFW to CHS

Envoy flew 171 of the 1,247 flights on DFW to CHS, about 14% of it. Its 91.7% on time is 21 points better than the route as a whole, which runs 71.0%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 91.7% to American at 66.4%. 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 Envoy runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 171 flights.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 91.7% on time across 171 flights.

Quarter by quarter Envoy on DFW to CHS held fairly steady: 90.8% in Oct–Dec 2025, 91.7% in Jan–Mar 2026 and 93.0% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Delay causes

Why Envoy runs late on this route

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 763 reported delay minutes.

Extreme weather
35%
Late-arriving aircraft
24%
National Airspace System
21%
Carrier
20%

Extreme weather accounts for 35% 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 5.6 times the usual weather exposure. The split is drawn from 763 reported delay minutes.

Cancellations sit at 1.75% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 1.8% 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.

The 987 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 runs 94.0% on time across 172 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 171 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 Envoy on DFW to CHS

Put together: treat all of this as provisional. 171 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 91.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 168 completed flights over 12 months sit behind that.
