These figures cover 201 flights between July 2025 and June 2026. Beyond the headline rate, 14.4% 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 ORD to SAV

SkyWest flew 201 of the 1,561 flights on ORD to SAV, about 13% of it. Its 68.2% on time is 9 points worse than the route as a whole, which runs 77.0%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from Envoy at 82.6% to SkyWest at 68.2%. Three 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 201 flights.

There are not enough flights in each departure window to split SkyWest's ORD to SAV record by time of day without the percentages moving on noise. The headline rate of 68.2% is the reliable figure here.

Across the year

SkyWest on ORD to SAV through the year

Jul–Sep 202588 flights69.0%
Oct–Dec 202525 flights—
Jan–Mar 202618 flights—
Apr–Jun 202670 flights65.2%

Scale runs 55% to 75%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 68.2% on time across 201 flights.

Split by quarter, SkyWest on ORD to SAV logged 88 flights in Jul–Sep 2025, 25 flights in Oct–Dec 2025, 18 flights in Jan–Mar 2026 and 70 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 68.2% annual figure is the one to use.

Across the week, Thursday is the strongest day at 70.0% on time and Friday the weakest at 57.6%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 5,485 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

51%

26%

Extreme weather
1%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,485 reported delay minutes here, that single category outweighs weather by 51 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,485 reported delay minutes.

Cancellations run at 2.99%, against 1.81% nationally. That is roughly 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.4% 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 773 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 is a different operation and performs like one: it runs 84.7% on time across 202 flights, 17 points above 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 17 points of difference.

One caution: this is a thin sample. 201 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 SAV

Put together: the delay figures matter less here than the 2.99% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 195 completed flights over 12 months sit behind that.
