Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on CLT to BHM lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 197 flights, with a median arrival 9 minutes early.

Set against the rest of the country, Envoy's CLT to BHM record is 5 points better than the US average of 77.6%. That gap is worth roughly 51 fewer late arrivals for every thousand flights.

Every carrier on CLT to BHM, 1,778 flights

These figures cover 197 flights between July 2025 and June 2026. The median arrival is 9 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 CLT to BHM

Envoy flew 197 of the 1,778 flights on CLT to BHM, about 11% of it. Its 82.7% on time is about level with the route as a whole at 83.8%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from SkyWest at 89.4% to American at 82.5%. 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 matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 82.7% on time across 197 flights.

Envoy on CLT to BHM did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.1% on time and its weakest Jan–Mar 2026 at 73.3%, a swing of 16 points on roughly 66 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Saturday is the strongest day at 87.1% on time and Friday the weakest at 77.4%. 10 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 2,755 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.

Extreme weather accounts for 33% 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 5.3 times the usual weather exposure. The split is drawn from 2,755 reported delay minutes.

46% 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 2,755 reported delay minutes here, that single category outweighs weather by 1 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 are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

6.1% 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 a little over an hour, which a normal layover absorbs.

At 350 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 8pm–5am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 87.3% on time across 197 flights, 5 points above 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 5 points of difference.

One caution: this is a thin sample. 197 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 CLT to BHM

Put together: treat all of this as provisional. 197 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 82.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 197 completed flights over 12 months sit behind that.
