Southwest Airlines doesn't have direct flights or a physical office in São Paulo, Brazil, as they primarily focus on North American routes (US, Mexico, Caribbean, Central America) and partner with other airlines for international connections; for São Paulo travel, you'd use their partners, contacting U.S. Southwest Customer Service (like the number 1-866-829-1086) or checking their website for partner flight info.
