Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on GSP to ORD carries a cancellation problem, not just a delay problem: 3.6% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 862 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on GSP to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Envoy against every carrier on GSP to ORD
Envoy flew 862 of the 1,870 flights on GSP to ORD, about 46% of it. Its 75.4% on time is about level with the route as a whole at 75.9%. Ranked by on-time rate it is number five of six carriers on the route, where the range runs from United at 100.0% to SkyWest at 71.4%. Four 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 24 points, against half a point between the best and worst carrier.
- 5am–8am169 flights84.5%
- 8am–11am76 flights65.2%
- 11am–2pm308 flights83.5%
- 2pm–5pm—
- 5pm–8pm138 flights60.2%
- 8pm–5am171 flights66.7%
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 60.2% on time, against 84.5% 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 11am–2pm window is the busiest, with 308 flights scheduled in it.
Across the year
Envoy on GSP to ORD through the year
January is the weak month at 50.0% on time, against 90.0% in September. 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. July was the busiest month here, with 93 flights.
Across the week, Wednesday is the strongest day at 80.2% on time and Friday the weakest at 71.3%, a spread of 9 points.
Arrival by arrival
How late Envoy on GSP to ORD runs when it is late
Envoy on GSP to ORD often beats the schedule: 275 of 824 completed flights, 33%, arrived 15 minutes or more early. The 203 late arrivals split 71 under half an hour, 63 between 30 and 60 minutes, and 69 an hour or more.

Share of 824 completed flights by arrival against schedule.
52 of 188 late departures made up the time and arrived on time, 28% of them. In the other direction, 67 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.
The worst days
Worst days for Envoy on GSP to ORD
The latest arrival of the period was on 1 August 2026, 7 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across August, November and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 August 2026 | 7 hours 52 minutes | Carrier |
| 29 November 2025 | 7 hours 10 minutes | Extreme weather |
| 29 August 2026 | 4 hours 59 minutes | Carrier |
| 30 November 2025 | 4 hours 47 minutes | Late-arriving aircraft |
| 1 May 2026 | 4 hours 36 minutes | Late-arriving aircraft |
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 14,000 reported delay minutes.
- 40%Late-arriving aircraft
- 26%National Airspace System
- 22%Carrier
- 12%Extreme weather
- 0%Security
Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 13,789 reported delay minutes.
40% 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 3 to one.
Cancellations run at 3.60%, against 1.89% 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
8.4% 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 about an hour, which a normal layover absorbs.
The 577 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 78.3% on time across 865 flights, within 3 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. 862 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 GSP to ORD
Put together: the delay figures matter less here than the 3.60% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 824 completed flights over 12 months sit behind that.
