The fastest way to LATAM Pass Gold isn't an application, it's spend: both LATAM-branded Mastercards in the US convert 30% of the miles you earn into Qualifying Points, and Gold takes 12,000 QP. At the 1x base earn rate that works out to roughly $40,000 in purchases (less if you route spend through the cards' bonus categories), and neither card documents a cap on the conversion.
The two cards run on identical terms. The LATAM Airlines Mastercard and the
LATAM Airlines World Elite Mastercard both carry no annual fee, both come from Cardless via First Electronic Bank, and both credit QP at the same 30% rate — the World Elite's marketing as the "faster" card refers to it earning more miles per dollar in bonus categories, not a richer points-to-QP conversion, despite what some marketing copy implies. Whichever card you're comparing, the QP math underneath is the same; the difference is only how quickly your everyday spend racks up the miles that feed it.
There's no separate challenge or status-match route documented here — Gold runs entirely on this card-spend mechanism, so the choice is really just which of the two cards fits your spending categories, not which path is easier.
