Depending on whether this is 3x per week or daily, is this one or two additional 777s at LGW or we going to see cuts to other LGW LH routes (which are mostly Caribbean now)?

Also, it seems quite appropriate for BA to add a South American route to LGW. This was after all where all UK-South American routes used to be when BCal had the UK monopoly rights.

It is also not that much of a trek to LHR, if the BA flight is otherwise convenient - one hour door to door on the coach.
