1-866-829-1086 Southwest Airlines Guayaquil Office
Southwest Airlines doesn't have a physical, standalone office in Guayaquil, Ecuador they primarily serve Latin America through partners or online, so you'll need to use their U.S. contact lines or website for booking/support, or connect through the airport (like Aeropuerto Guayaquil - GYE) via partners like Aeromexico or Avianca for actual flight support if flying to/from Ecuador.
