BoA has POS restricted fares that need to be purchased in Bolivia - does anyone have experience/know how to do this? I managed to do so for Chile domestic flights on LATAM by using the Chile site, but don't find this option for BoA. Google flights shows me the cheaper price (verified on ITA Matrix that the diff is because of POS restrictions).
Only a $25 or so price diff on UYU-LPB, but if the option exists...
