Other North & South America Frequent Flyer Programs - Lan - Certain fare bases give "preferente" treatment?

I just booked something with a B fare bucket - it is the first time that the entire economy seatmap opened up for me. Do you know if this is also going to cause a "preferente" print on the boarding pass? I have no Lanpass nor OW status. (I ask out of carry-on concerns.)

What's the fare base code?

AFAIK "preferente" is only used for LAN/OW (ruby or better) status OR Business Class Tickets.
"FF" (Coach), "EV" and "EJ" (Business) fare bases will always open "preferred" seating if available, but I don't believe you will get any additional bag allowance.

Thanks. I just wondered if "preferente" would print on the BP and that the carry-on police would be not so diligent.
