SkyWest on AVL to ORD sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.3%. The late ones land an hour and a half behind schedule. That rests on 790 flights, with a median arrival 3 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on AVL 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
SkyWest against every carrier on AVL to ORD
SkyWest flew 790 of the 1,513 flights on AVL to ORD, most of the route. Its 73.7% on time is about level with the route as a whole at 73.3%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from PSA at 100.0% to Republic at 71.9%. 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 36 points, against half a point between the best and worst carrier.
- 5am–8am280 flights85.5%
- 8am–11am162 flights83.3%
- 11am–2pm72 flights80.0%
- 2pm–5pm51 flights74.5%
- 5pm–8pm225 flights49.1%
- 8pm–5am—
Scale runs 40% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 49.1% on time, against 85.5% 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 280 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 78.2% on time and Tuesday the weakest at 70.9%, a spread of 7 points.

Share of 763 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 141 departures that left 15 minutes late or more, only 14 made it up before arrival. In the other direction, 74 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 SkyWest on AVL to ORD
The latest arrival of the period was on 27 December 2025, 18 hours 41 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 |
|---|---|---|
| 27 December 2025 | 18 hours 41 minutes | Late-arriving aircraft |
| 30 December 2025 | 12 hours 18 minutes | Carrier |
| 7 March 2026 | 11 hours 22 minutes | Late-arriving aircraft |
| 18 June 2026 | 9 hours 37 minutes | Extreme weather |
| 9 May 2026 | 7 hours 1 minute | Late-arriving aircraft |
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.
- 33%Late-arriving aircraft
- 33%Carrier
- 26%National Airspace System
- 9%Extreme weather
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 85.5% on time here. The split is drawn from 17,144 reported delay minutes.
No single cause dominates. late-arriving aircraft at 33%, carrier at 33% and national airspace system at 26% 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 2.66%, against 1.89% 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
11.1% 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 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.
The return leg is a different operation and performs like one: it runs 70.0% on time across 789 flights, 4 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 790 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. 790 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 73.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 763 completed flights over 12 months sit behind that.
