Departure window
The best time of day to leave BNA in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 39 points, against 19 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am2,003 flights89.0%
- 8am–11am1,366 flights88.8%
- 11am–2pm1,561 flights73.3%
- 2pm–5pm1,831 flights56.5%
- 5pm–8pm1,642 flights50.1%
- 8pm–5am1,056 flights54.4%
Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 50.1% on time, against 89.0% 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 2,003 flights scheduled in it.
Across the week, Saturday is the strongest day at 78.7% on time and Monday the weakest at 60.3%. 18 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at BNA in July
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 81.0% of the time; American Airlines manages 62.2%. Sample sizes sit next to every figure, because a two-point gap across 885 flights means less than a ten-point one.

Republic Airways cancels 8.3% 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 July
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 223,000 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.
- 47%Late-arriving aircraft
- 26%Carrier
- 21%National Airspace System
- 7%Extreme weather
- 0%Security
47% 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 223,000 reported delay minutes here, that single category outweighs weather by 7 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 222,547 reported delay minutes.
Cancellations sit at 2.09% against a national 2.45%, which is ordinary. Diversions add another 0.42%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.5% of arrivals land a full hour or more behind schedule, against 12.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from BNA in July
For a July trip through BNA: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 89.0% on time, and with 12.5% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
