The flight path crosses the Atlantic Ocean for roughly 5-6 hours with no significant landmarks visible—primarily open ocean. The route typically passes south of the Caribbean islands and north of the Amazon Basin.

The interior approach to São Paulo crosses the Brazilian plateau and scattered cloud cover over inland regions before the final descent into the São Paulo basin.
