Envoy on ORD to GSO lands a B, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 947 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 ORD to GSO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The worst days
Worst days for Envoy on ORD to GSO
The latest arrival of the period was on 2 April 2026, 6 hours 32 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 April 2026 | 6 hours 32 minutes | Late-arriving aircraft |
| 18 January 2026 | 6 hours 7 minutes | Extreme weather |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 58% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 18%National Airspace System
- 13%Extreme weather
- 11%Carrier
Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 14,429 reported delay minutes.
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 5 to one.
Cancellations sit at 2.43% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
8.9% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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 79.0% on time across 946 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. 947 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 GSO
Put together: treat all of this as provisional. 947 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 78.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 924 completed flights over 12 months sit behind that.
