Why BNA runs the way it does
Southwest Airlines flew 52.0% of BNA departures in the window, and its flights ran 20.2% late, in line with the airport as a whole. With one carrier that large, BNA's delay record largely follows how Southwest Airlines runs its schedule.
BNA delays peak in July (29.5%), June (28.1%) and May (24.8%) and are lowest in February (15.6%). That shape is consistent with the summer thunderstorm season, when convective weather builds through the afternoon and slows arrivals and departures.
Delays build through the day: 11.2% of flights scheduled before 8 AM ran late against 30.8% after 8 PM. That is the pattern BTS describes as late-arriving aircraft, where a previous flight with the same aircraft arriving late makes the next departure late.
