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 324 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm1 flights—
- 2pm–5pm272 flights88.7%
- 5pm–8pm51 flights80.4%
- 8pm–5am—
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 2pm–5pm slot at 88.7% on time, ahead of 5pm–8pm at 80.4%. 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 2pm–5pm window is the busiest, with 272 flights scheduled in it.

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 58% of the 1,731 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 24%Carrier
- 11%National Airspace System
- 8%Extreme weather
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,731 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 1,731 reported delay minutes.
Cancellations sit at 1.85% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 2.2% land an hour or more behind schedule, against 8.3% 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 736 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.
The return leg runs 87.8% on time across 324 flights, within half a point 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. 324 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 EYW to CLT
Put together: treat all of this as provisional. 324 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 87.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 317 completed flights over 12 months sit behind that.
