Well, Dad flew less last year so he's not renewing PSilver because of the Perú rules (he did get 40.000+ km and 4 J segments, so he would've requalified under the most-countries rules but the Perú rules at the time were 6 J segments.) I ended up using mostly his kms to travel, so I didn't requalify for Premium.
Funny thing is that some km from late last year didn't post and I requested them a couple of weeks ago. When they posted, they now show up under 2013 (but with 0 segments)... he seems to have rolled over some kms without intending to. I also had to fill out the form for mom's flights: they posted but haven't rolled over to 2013 (they don't show up in the Summary of activities valid for qualifying for superior member categories for 2012 or 2013)

----------
For countries other than Perú I've only noticed the some pages haven't changed and but most mention that TAM segments / kms are now qualifying.

other changes

Premium Silver (others)
40.000 km + 4 medium or long haul segments on LAN / TAM Business
to
40.000 km + 6 medium or long haul segments on LAN / TAM Business

Comodoro (others)
90.000 km + 6 medium or long haul segments on LAN Premium Business
to
80.000 km + 8 medium or long haul segments on LAN / TAM Business

The site is so inconsistent... Some country-sites use a different URL, they have headings that change color midpage, missing headings (two ways of qualifying get stuck under one heading, like on this page), mentions that the page was updated in 2010 or 2011 when there have been recent updates... I could go on, but it's exhausting. Good night everyone! I'll keep track to check if the rest of the pages are updated.
