Envoy on GSO to ORD lands a B, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 946 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on GSO to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Envoy against every carrier on GSO to ORD
Envoy flew 946 of the 1,560 flights on GSO to ORD, most of the route. Its 79.0% on time is 2 points better than the route as a whole, which runs 77.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 87.3% to SkyWest at 72.9%.

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 24 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm281 flights79.1%
- 2pm–5pm29 flights—
- 5pm–8pm112 flights64.1%
- 8pm–5am161 flights68.9%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 64.1% on time, against 88.5% 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 5am–8am window is the busiest, with 363 flights scheduled in it.
Across the year
Envoy on GSO to ORD through the year
December is the weak month at 69.9% on time, against 92.7% in May. 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. August was the busiest month here, with 92 flights.
Across the week, Thursday is the strongest day at 81.4% on time and Sunday the weakest at 74.6%, a spread of 7 points.

The worst days
Worst days for Envoy on GSO to ORD
The latest arrival of the period was on 4 July 2026, 14 hours 44 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 July 2026 | 14 hours 44 minutes | Carrier |
| 11 May 2026 | 11 hours 29 minutes | Late-arriving aircraft |
| 8 October 2025 | 9 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 45% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 23%National Airspace System
- 18%Carrier
- 15%Extreme weather
Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 17,169 reported delay minutes.
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 2.75%, against 1.89% nationally. That is roughly one flight in 40 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
9.8% 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.
The 589 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 78.0% on time across 947 flights, within about 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. 946 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 GSO to ORD
Put together: treat all of this as provisional. 946 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 79.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 917 completed flights over 12 months sit behind that.
