  This study investigates price seasonality in the Brazilian air transport
industry, emphasizing the impact of the COVID-19 pandemic on domestic airline
pricing strategies. Given potential shifts in demand patterns following the
global health crisis, this study explores possible long-term structural changes
in the seasonality of Brazilian airfare. We analyze an open dataset of domestic
city pairs from 2013 to 2023, employing an econometric model developed using
Stata software. Our findings indicate alterations in seasonal patterns and
long-term trends in the post-pandemic era. These changes underscore potential
shifts in the composition of leisure and business travelers, along with the
cost pressures faced by airlines.
