Every carrier on CHS to DFW, 1,250 flights

These figures cover 172 flights between July 2025 and June 2026. The median arrival is 18 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 CHS to DFW

Envoy flew 172 of the 1,250 flights on CHS to DFW, about 14% of it. Its 94.0% on time is 14 points better than the route as a whole, which runs 80.5%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Envoy at 94.0% to Frontier at 77.8%. 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 172 flights.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 94.0% on time across 172 flights.

Quarter by quarter Envoy on CHS to DFW held fairly steady: 95.3% in Oct–Dec 2025, 95.0% in Jan–Mar 2026 and 90.5% in Apr–Jun 2026. A spread of 5 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

One category carries most of the weight here. Late-arriving aircraft accounts for 85% of the 944 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.

85% 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 944 reported delay minutes here, that single category outweighs weather by 85 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 944 reported delay minutes.

Cancellations sit at 1.74% against a national 1.81%, which is ordinary. Diversions add another 1.74%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.6% 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 91.7% on time across 171 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. 172 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 CHS to DFW

Put together: treat all of this as provisional. 172 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 94.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 166 completed flights over 12 months sit behind that.
