I was just able to pre-select preferred seats on an award tix (previously prohibited) at T minus a couple of weeks.

Reward flight Lan Colombia and Lan Peru A319/A320: Able to select gold seats (1ABC) weeks ahead.
As well, as we suspected they were planning, looks like they have now activated pay for preferred seat selection (rows 2-4). $5.90 usd. Of course, some Elites still have free preferred seat selection.
The new codes Lan Colombia and Lan Peru A319/A320 are:
Gold = Asiento exclusivo por categoría Emerald (Row 1 seats ABC and K. Sometimes 2C)
Blank =Asiento disponible
Blue = Asiento exclusivo por categoría Emerald sin costo, otherwise $5.90 Rows 2-4
X'd out = Asiento no disponible

Unable to preselect seats on any X (Base) fare, of course.

As they recently announced, I was able to select a gold preferred seat for international flight (MIA-LIM 767) T award tix in Y. 13AC and 24ACD (except exit row 24 selection the “I meet the criteria” buttom failed).

Other International flight MIA-BOG 767, of course able to select revenue J seats weeks ahead, no preferred gold seats... because it is J.

Bottom line, go to your My Trips, Ver detalle y otros servicios [+], Selección de asiento and see what is now possible (and report back?).
