London to Buenos Aires goes non-stop, and on to Santiago
From 28 March 2027 British Airways will fly London Heathrow to Buenos Aires daily and non-stop, with the aircraft carrying on to Santiago. Buenos Aires is reached today on a routing through Rio de Janeiro, which becomes a dedicated daily flight of its own on the same date. The airline puts the summer 2027 change at about 25 per cent more seat kilometres across Latin America.
