Thank you all for the feedback.

I am based mostly in BCN but split time between BCN MIA and PDP (Punta del Este, Uruguay). For personal reasons have not done much travel this year. So was trying to maximize miles points. I am also switching from AA Advantage, currently EMERALD. Flirted with the idea of going with SKYTEAM but much prefer the value in OW Emerald status. So still deciding wether to opt for BA, IB OR LATAM program. Looks like will go for BAEC as will be able then to maximize transfers from CC usage to one program.

With that in mind was trying to look at creative routings and was coming with good options at about the same prices in J. Was trying to avoid flying PE in order to get better return on TP (miles). Some of the options were

MAD/BCN LIM GRU MVD/PDPD
MAD/BCN LIM SCL MVD/PDP
MAD/BCN GRU MVD/PDP
MAD SCL MVD
Connecting in LHR also came out but does not offer any competitive advantage.

Good to know about the 777 as this is an option connecting from LIM.

The next four months will have 2 trips to Uruguay and while there one to the US reason why asking in the LATAM forum as looks like will concentrate those trips with LATAM.

As as a side note since was asking about the hard product my last flight was wth IB A330 and their new J product is quite tight and uncomfortable.

Thanks, JC
