For Avianca’s lifemiles members, 2025 starts off well as the program has introduced unilateral improvements.
Members now receive significantly more (revenue-based) miles on all fares on Avianca flights, including for the first time miles at the cheapest Basic/Light fares. On the other end of the scale, the credits in Business Class have been increased from 7 miles to 10 miles per USD.

If this motivates you to engage more with the Star Alliance program in 2025, the promotion for purchasing miles running until January 31 might be of interest, where the program is traditionally always aggressive: For each purchase, you receive a bonus of at least 110%, which increases to 160% starting from the purchase of 36,000 miles. Such a bonus can make purchasing miles definitely worthwhile.
