LATAM Airlines operates the Boeing 787-9 Dreamliner on the route between Sao Paulo Guarulhos and Mexico City International Airport, offering a modern widebody cabin on a long South American trunk route. For 2026 frequent flyers booking this route with cash, points, or a combination of both, understanding the economy class experience, fare structure, and the taxes versus cash fare equation helps determine whether to pay cash or redeem miles.
The LATAM 787-9 is configured in a three-class layout with Premium Business, Premium Economy, and Economy. The Economy cabin features seats in a 3-3-3 configuration with 31 to 32 inches of pitch and 17 inches of width. The Dreamliner’s larger windows, improved cabin pressure, and higher humidity levels contribute to a more comfortable long-haul experience compared to older aircraft types. Each seat includes a personal entertainment screen with a selection of movies, TV shows, and music. Wi-Fi is available for purchase on most LATAM 787-9 aircraft. Meal service includes a main meal and a lighter snack before landing on the approximately 9-hour flight, with complimentary beer, wine, and soft drinks.
Cash fares on the GRU to MEX route vary significantly by season, typically ranging from 400 to 800 dollars roundtrip in economy class. LATAM Pass points and partner programs including Delta SkyMiles, British Airways Avios, and Alaska Airlines Mileage Plan can all be used to book LATAM award tickets, though award availability varies by program. Award taxes and fees on LATAM-operated flights are generally reasonable, with international departure taxes from Brazil and Mexico comprising the bulk of the cash component. A roundtrip economy award may incur 80 to 120 dollars in taxes and fees.
LATAM Pass has transitioned away from the oneworld alliance, but the airline maintains bilateral partnerships with Delta Air Lines, Alaska Airlines, British Airways, and several other carriers. Delta SkyMiles offers LATAM award bookings through its website and can be a strong redemption option for U.S.-based travelers, especially when dynamic pricing presents favorable rates. British Airways Avios can also be used for LATAM awards, with distance-based pricing that favors shorter segments within South America.
