Another card, the LATAM Visa Signature® Card, allows to earn double points on LATAM Airlines ticket purchases and 1 points for every $1 spend. If you want to earn more, consider general travel rewards credit cards. These cards are more flexible in earning rewards and may give you up to 3x miles or points on your purchases.
