These figures cover 783 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Envoy against every carrier on ORD to BNA
Envoy flew 783 of the 5,021 flights on ORD to BNA, about 16% of it. Its 74.8% on time is 6 points better than the route as a whole, which runs 68.6%. Ranked by on-time rate it is number three of nine carriers on the route, where the range runs from PSA at 100.0% to SkyWest at 61.0%. Four of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 76.6% of the time; SkyWest Airlines manages 61.0%. Sample sizes sit next to every figure, because a two-point gap across 1,467 flights means less than a ten-point one.

SkyWest Airlines cancels 3.9% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
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 16 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am43 flights79.1%
- 8am–11am154 flights84.8%
- 11am–2pm166 flights72.1%
- 2pm–5pm174 flights74.1%
- 5pm–8pm146 flights68.8%
- 8pm–5am100 flights71.1%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 84.8% of the time, against 68.8% for the evening window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 174 flights scheduled in it.
Across the year
Envoy on ORD to BNA through the year
December is the weak month at 64.0% on time, against 82.3% in June. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 162 flights.
Across the week, Saturday is the strongest day at 86.4% on time and Monday the weakest at 67.6%. 19 points is a smaller lever than departure hour, but it is free.
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 11,000 reported delay minutes.
- 35%Late-arriving aircraft
- 34%National Airspace System
- 19%Extreme weather
- 13%Carrier
Extreme weather accounts for 19% 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 3.1 times the usual weather exposure. The split is drawn from 11,415 reported delay minutes.
35% 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 11,000 reported delay minutes here, that single category outweighs weather by 2 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 run at 3.19%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
8.6% 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 about an hour, which a normal layover absorbs.
At 409 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 8am–11am window matters as much as it does.
The return leg runs 73.0% on time across 782 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. 783 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 ORD to BNA
Put together: the delay figures matter less here than the 3.19% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 757 completed flights over 12 months sit behind that.
