Avianca LifeMiles is a points currency than can be used on any Star Alliance airline including United, Turkish, Lufthansa, Swiss, ANA, and many more. During Black Friday last week, they were selling LifeMiles for super cheap! 25k miles for 330 dollars, 100k miles for 1320 dollars, etc. Because one of my dream destinations is to go to the Galapagos Islands next year (an amazing group of islands next to Ecuador known for their amazing wildlife), I bought some of these miles to help me get there for cheap! Normally, a round-trip ticket from Boston costs at least 700 dollars. With this promotion, I could fly round trip from Boston to SCY for under 500 dollars! I You need 35k LifeMiles to book the ticket, which during black friday was about $460!
Another amazing way to use LifeMiles is for tickets within Latin America. Some routes cost as little as 3k miles! I purchased Bogota to the Galapagos Islands for only 10k Lifemiles one way and later bought a ticket from Lima to San Jose, CR for only 12k miles!
To top it off, purchasing LifeMiles counts as Airline on your credit card, so I was able to buy 65k miles and also net 4k AMEX points for the purchase (about a 50 dollar value)! You know you're a travel geek, when your entire Black Friday shopping consists of buying Avianca LifeMiles!
