Do LATAM Pass Miles have an expiration date?
Miles are valid for a period of 36 months from the date of the last flight taken in which 1 or more LATAM Pass Miles were earned. Miles earned expire the last day of the 36th month.
If you earned miles on flights with oneworld or other associated airlines, associated companies or from purchasing any LATAM Airlines products or services, they are valid for a period of 3 calendar years, expiring on December 31 of the third year in which they were earned.
You can extend the duration of your miles, whether obtained from traveling, from purchasing LATAM services and products, from oneworld airlines or associated companies, if you fly with LATAM Airlines within the 36 months of validity and earn 1 or more miles on that flight. If you do this, all your miles automatically renew their extension for another 36 months.
