Ideas for routes to Latin America

We would like to pitch some ideas on how to operate flights from the Philippines to Latin America, as non-stop flights are still impossible even for jumbo airliners like the Airbus A330, Boeing 777, Airbus A340, Airbus A350, and perhaps Airbus A380 (correct me if I’m wrong):

Manila to Sao Paolo via Johannesburg
Manila to Rio de Janeiro via Johannesburg
Manila to Mexico City (non-stop)
Manila to Montevideo via Johannesburg
Manila to Buenos Aires via Johannesburg
Manila to Santiago via Auckland
Manila to San Juan via Mexico City
Manila to Quito via Auckland
Manila to Lima via Auckland
Manila to Asuncion via Auckland
Manila to Cocachamba via Johannesburg
Manila to La Paz via Johannesburg
Manila to Santa Cruz-Viru Viru via Johannesburg
Manila to Bogota via Mexico City
Manila to Caracas via Mexico City
Manila to Panama City via Mexico City
Manila to Havana via Mexico City
Manila to Managua via Mexico City
Manila to San Salvador via Mexico City
Manila to San Jose via Mexico City
Manila to Tegucigalpa via Mexico City
Manila to Santo Domingo via Mexico City
Manila to Guatemala City via Mexico City

The above mentioned are for trans-Pacific routes. For a probably less costly and more profitable one, consider Madrid or Lisbon as possible stopovers.

These are for the flag carrier Philippine Airlines should the day come they would ever decide to expand to the region. At present they have a fleet of eight Boeing 777-300s which are primarily used to flights in the United States, Canada, and UK, and future expansion to Rome, Amsterdam, Frankfurt, and Paris. They also have orders for six Airbus A350-500s which will most likely be deployed to these destinations.

At present Latin American carriers have limited presence in the Asian region (for example, Aeromexico has flights to Shanghai and Tokyo), but for expansion plans they might consider the Philippines as it is a cultural cousin.

Will this become feasible in the future? Share us your thoughts.
