These figures cover 739 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
SkyWest against every carrier on AVL to ORD
SkyWest flew 739 of the 1,398 flights on AVL to ORD, most of the route. Its 71.6% on time is about level with the route as a whole at 71.9%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from PSA at 100.0% to Republic at 68.6%. Two 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 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 43 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am286 flights85.4%
- 8am–11am122 flights81.2%
- 11am–2pm75 flights79.5%
- 2pm–5pm51 flights74.5%
- 5pm–8pm205 flights42.6%
- 8pm–5am—
Scale runs 35% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 42.6% on time, against 85.4% 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 286 flights scheduled in it.
Across the year
SkyWest on AVL to ORD through the year
December is the weak month at 37.8% on time, against 85.3% 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. April was the busiest month here, with 115 flights.
Across the week, Friday is the strongest day at 74.8% on time and Sunday the weakest at 66.7%. 8 points is a smaller lever than departure hour, but it is free.
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 17,000 reported delay minutes.
- 34%Late-arriving aircraft
- 33%Carrier
- 24%National Airspace System
- 9%Extreme weather
- 0%Security
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.4% on time here. The split is drawn from 16,707 reported delay minutes.
No single cause dominates. late-arriving aircraft at 34%, carrier at 33% and national airspace system at 24% split the 17,000 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around.
Cancellations run at 2.57%, against 1.81% nationally. That is about 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 536 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 70.1% on time across 740 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. 739 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 AVL to ORD
Put together: treat all of this as provisional. 739 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 71.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 714 completed flights over 12 months sit behind that.
