These figures cover 168 flights between July 2025 and June 2026. The median arrival is 8 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

Republic against every carrier on ORD to SAV

Republic flew 168 of the 1,561 flights on ORD to SAV, about 11% of it. Its 69.4% on time is 8 points worse than the route as a whole, which runs 77.0%. Ranked by on-time rate it is number four 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 Republic 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 168 flights.

There are not enough flights in each departure window to split Republic's ORD to SAV record by time of day without the percentages moving on noise. The headline rate of 69.4% is the reliable figure here.

Across the year

Republic on ORD to SAV through the year

Jul–Sep 20257 flights—
Oct–Dec 202523 flights—
Jan–Mar 202686 flights67.9%
Apr–Jun 202652 flights72.5%

Scale runs 60% to 80%. 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 69.4% on time across 168 flights.

Split by quarter, Republic on ORD to SAV logged 7 flights in Jul–Sep 2025, 23 flights in Oct–Dec 2025, 86 flights in Jan–Mar 2026 and 52 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 69.4% annual figure is the one to use.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Carrier accounts for 46% of the 3,455 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, 46%, 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 1,598 of the 3,455 delay minutes reported here. The split is drawn from 3,455 reported delay minutes.

Cancellations run at 4.17%, against 1.81% nationally. That is about one flight in 25 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

7.5% 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 a little over 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 83.4% on time across 167 flights, 14 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 14 points of difference.

One caution: this is a thin sample. 168 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 Republic on ORD to SAV

Put together: the delay figures matter less here than the 4.17% cancellation rate. A late arrival costs you a little over an hour; 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. 160 completed flights over 12 months sit behind that.
