This route sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land about 50 minutes behind schedule. That rests on 921 BNA to SAV flights, with a median arrival 1 minute early.
Best time to fly BNA to SAV: a 11am–2pm departure, ideally on a Tuesday. Flights in that window arrived on time 96.9% of the time and Tuesday flights 78.3%, against 74.9% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 921 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

The 8pm–5am window is where this operation falls apart: 62.6% on time, against 96.9% for the 11am–2pm 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 8am–11am window is the busiest, with 331 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 33 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
July is the worst month at 56.8% on time, 33 points below February, the best at 90.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 89 flights.
Across the week, Tuesday is the strongest day at 78.3% on time and Sunday the weakest at 72.1%, a spread of 6 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 59% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 30%Carrier
- 9%National Airspace System
- 1%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 59 to one. The split is drawn from 11,431 reported delay minutes.
Cancellations are rare at 0.65%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here actually costs
6.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 50 minutes, which a normal layover absorbs.
At 417 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 80.0% on time across 922 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 921 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 this route
Put together: treat all of this as provisional. 921 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 74.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 913 completed flights over 12 months sit behind that.
Common questions
BNA to SAV questions
How often is BNA to SAV delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 25.1% of the 921 flights in this analysis, against 22.7% nationally. Delayed flights are late by about 50 minutes on average.
How reliable is BNA to SAV compared with the rest of the country?
74.9% of flights arrive on time here against a national 77.3%, a difference of 2 points against it. That is worth a C+ on this site's grading scale.
What time of day has the fewest delays on BNA to SAV?
The 11am–2pm departure window is the strongest at 96.9% on time. The 8pm–5am window is the weakest at 62.6%, 34 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on BNA to SAV?
July is the weakest month at 56.8% on time, compared with 90.0% in February. Across the year that is 33 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
