SkyWest on SAV to ORD earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%.

Set against the rest of the country, SkyWest's SAV to ORD record is 7 points better than the US average of 77.6%. That gap is worth roughly 71 fewer late arrivals for every thousand flights.

Every carrier on SAV to ORD, 1,563 flights

These figures cover 202 flights between July 2025 and June 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

SkyWest against every carrier on SAV to ORD

SkyWest flew 202 of the 1,563 flights on SAV to ORD, about 13% of it. Its 84.7% on time is 9 points better than the route as a whole, which runs 75.6%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from SkyWest at 84.7% to United at 69.2%. 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 202 flights.

There are not enough flights in each departure window to split SkyWest's SAV to ORD record by time of day without the percentages moving on noise. The headline rate of 84.7% is the reliable figure here.

Across the year

SkyWest on SAV to ORD through the year

Jul–Sep 202588 flights85.1%
Oct–Dec 202526 flights—
Jan–Mar 202618 flights—
Apr–Jun 202670 flights81.8%

Scale runs 75% to 90%. 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 84.7% on time across 202 flights.

Split by quarter, SkyWest on SAV to ORD logged 88 flights in Jul–Sep 2025, 26 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 84.7% annual figure is the one to use.

Across the week, Friday is the strongest day at 81.8% on time and Saturday the weakest at 75.0%. 7 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. Carrier accounts for 51% of the 1,879 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.

Extreme weather

The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 960 of the 1,879 delay minutes reported here. The split is drawn from 1,879 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 89.8% on time here.

Cancellations run at 2.97%, 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

5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 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 68.2% on time across 201 flights, 17 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 17 points of difference.

One caution: this is a thin sample. 202 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 SAV to ORD

Put together: the delay figures matter less here than the 2.97% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 196 completed flights over 12 months sit behind that.
