Would any of this airports in South America be viable enough to be served from LHR by BA
Brasília International Airport
Comodoro Arturo Merino Benítez International Airport
El Dorado International Airport
Jorge Chávez International Airport
José Joaquín de Olmedo International Airport
Mariscal Sucre International Airport
Salvador-Deputado Luís Eduardo Magalhães International
Salgado Filho International Airport
Silvio Pettirossi International Airport
Recife/Guararapes-Gilberto Freyre International Airport
All of these are LATAM hubs, what I am suggesting that IAG and LATAM should agree that LATAM serves Mainland-Europe/Ireland from LATAM and BA serves those hubs from the UK, this would mean IB withdraws services from MAD to LATAM hubs (although it would still codeshare LATAM flights to MAD and if launched BCN)
