Envoy on LEX to ORD lands a B, level with the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 296 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on LEX to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Ranked by on-time rate it is number two of three carriers on the route, where the range runs from PSA at 82.6% to SkyWest at 72.4%. One 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

- 8am–11am84 flights80.7%
- 11am–2pm44 flights84.1%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.4% on time, against 86.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 96 flights scheduled in it.

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 56% of the 6,069 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 33%National Airspace System
- 10%Carrier
- 1%Security
- 0%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,069 reported delay minutes here, that single category outweighs weather by 56 to one. The split is drawn from 6,069 reported delay minutes.
33% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,986 minutes out of 6,069, against a national NAS share of 21%.
Cancellations sit at 1.35% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
9.6% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 323 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 72.9% on time across 295 flights, 4 points below 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 4 points of difference.
One caution: this is a thin sample. 296 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 LEX to ORD
Put together: treat all of this as provisional. 296 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 76.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 292 completed flights over 12 months sit behind that.
