Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.

Republic on SAV to ORD lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 167 flights, with a median arrival 11 minutes early.

Set against the rest of the country, Republic's SAV to ORD record is 6 points better than the US average of 77.6%. That gap is worth roughly 58 fewer late arrivals for every thousand flights.

These figures cover 167 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

Republic against every carrier on SAV to ORD

Republic flew 167 of the 1,563 flights on SAV to ORD, about 11% of it. Its 83.4% on time is 8 points better than the route as a whole, which runs 75.6%. Ranked by on-time rate it is number two 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 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 167 flights.

There are not enough flights in each departure window to split Republic's SAV to ORD record by time of day without the percentages moving on noise. The headline rate of 83.4% is the reliable figure here.

Across the year

Republic on SAV to ORD through the year

  • Jul–Sep 20257 flights
  • Oct–Dec 202522 flights
  • Jan–Mar 202686 flights83.1%
  • Apr–Jun 202652 flights86.5%

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 83.4% on time across 167 flights.

Split by quarter, Republic on SAV to ORD logged 7 flights in Jul–Sep 2025, 22 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 83.4% annual figure is the one to use.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. National Airspace System accounts for 44% of the 1,585 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.

  • Late-arriving aircraft
    25%
  • Extreme weather

44% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 695 minutes out of 1,585, against a national NAS share of 21%. The split is drawn from 1,585 reported delay minutes.

Cancellations sit at 2.40% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

6.1% 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 69.4% on time across 168 flights, 14 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 14 points of difference.

One caution: this is a thin sample. 167 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 SAV to ORD

Put together: treat all of this as provisional. 167 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 83.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 163 completed flights over 12 months sit behind that.
