2São Paulo-Guarulhos International Airport (São Paulo, Brazil)

Brazil’s busiest airport, São Paulo-Guarulhos International Airport, frequently faces complaints about its overcrowded terminals, long security lines, and poor baggage handling. Delays are common, and passengers often experience difficulties navigating the airport due to poor signage and limited staff assistance.

Public transportation to and from the airport is inconvenient, and the facilities inside the terminals are often dirty or in need of repair. With insufficient dining and shopping options, it is considered one of the least passenger-friendly airports in South America.
