It’s being reported that Delta will purchase 20% of LATAM. As a result the airline will leave OneWorld (hence the BA connection).

“LATAM will be leaving the OneWorld alliance, but it was not immediately clear whether it would join SkyTeam, the group that includes Delta and its partners.”

I wonder what effect this will have on BA’s Southern America ops. They were never that strong and now losing their partner can’t help.
