Nashville International Airportsaw 81% of its flights depart on time in December 2023, according to the latest federal data.
Why it matters: That represents a significant improvement from the 67% rating a year prior, when winter weather led to a travel meltdown, in large part because of problems at Southwest Airlines.
Yes, but: BNA continued to rank below the national average of 83% in December 2023.
In December 2022, Southwest's problems dragged the industry-wide average down to about 70% for the month.
Between the lines: A variety of factors, from weather to issues at a particular airline, can affect each airport's on-time performance.
