SkyWest against every carrier on ORD to GSO
SkyWest flew 528 of the 1,560 flights on ORD to GSO, about 34% of it. Its 71.1% on time is 5 points worse than the route as a whole, which runs 76.1%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Republic at 86.2% to SkyWest at 71.1%.

Departure window
When SkyWest 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–8am1 flights—
- 8am–11am31 flights80.6%
- 11am–2pm215 flights82.1%
- 2pm–5pm47 flights72.1%
- 5pm–8pm213 flights57.6%
- 8pm–5am21 flights—
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 57.6% on time, against 82.1% for the 11am–2pm 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 215 flights scheduled in it.
Across the year
SkyWest on ORD to GSO through the year
December is the weak month at 58.1% on time, against 90.0% in October. 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 87 flights.
Across the week, Friday is the strongest day at 78.6% on time and Wednesday the weakest at 61.8%, a spread of 17 points.

Share of 509 completed flights by arrival against schedule.
16 of 96 late departures made up the time and arrived on time, 17% 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 GSO.

The latest arrival of the period was on 7 March 2026, 5 hours 27 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |

Delay causes
Why SkyWest 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 8,995 reported delay minutes.
- 39%Carrier
- 29%Late-arriving aircraft
- 28%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,489 of the 8,995 delay minutes reported here. The split is drawn from 8,995 reported delay minutes.
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
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 72.9% on time across 529 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. 528 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 SkyWest on ORD to GSO
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 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 509 completed flights over 12 months sit behind that.
