BNA in December 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 better than the national rate of 73.2%.

BNA across all twelve months

These figures cover 8,776 departures from Nashville International in December 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

December next to BNA's other months

Against BNA's own year, December ran about a point worse than the twelve-month rate of 76.2%, which makes it number nine of twelve months, best first. Either side of it, November ran 79.0% on time and January 84.3%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave BNA in December

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,682 flights86.2%
  • 8am–11am1,581 flights83.9%
  • 11am–2pm1,506 flights77.3%
  • 2pm–5pm1,681 flights68.4%
  • 5pm–8pm1,564 flights64.5%
  • 8pm–5am762 flights61.9%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 61.9% on time, against 86.2% for the 5am–8am 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 5am–8am window is the busiest, with 1,682 flights scheduled in it.

Across the week, Wednesday is the strongest day at 86.4% on time and Sunday the weakest at 68.4%. 18 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at BNA in December

The choice of carrier is not cosmetic here. American Airlines arrives on time 81.2% of the time; Republic Airways manages 69.1%. Sample sizes sit next to every figure, because a two-point gap across 665 flights means less than a ten-point one.

Delta Air Lines cancels 3.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes

What held BNA up in December

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 140,000 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
    49%
  • Carrier
    33%
  • National Airspace System
    17%
  • Extreme weather
    1%
  • Security
    0%

49% 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 140,000 reported delay minutes here, that single category outweighs weather by 42 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 139,620 reported delay minutes.

Cancellations sit at 0.99% against a national 1.55%, which is ordinary. Diversions add another 0.22%.

8.0% of arrivals land an hour or more late, close to the national 10.0%. 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.

What to do with this

Flying from BNA in December

For a December trip through BNA: expect 74.9% on time and 0.99% cancelled, going by December 2025. The 5am–8am window was the strongest part of the day.
