The Avianca LifeMiles has just launched the latest buy miles promotion and you might find it useful if you want to top up your existing miles for award redemptions.
Buy LifeMiles With up to a 135% Bonus

Through September 27, 2023, the LifeMiles program is offering up to a 135% bonus when purchasing miles. With this promotion, members are able to receive bonus miles in tiers:
- Purchase between 1,000 to 20,000 miles and get a 125% bonus
- Purchase between 21,000 to 200,000 miles and get a 135% bonus
To buy LifeMiles with bonuses, you have to log in to your LifeMiles account and proceed to the buy miles page.
How Many Miles Can You Purchase
The LifeMiles must be purchased in increments of 1,000 and you can buy up to 200,000 miles per calendar year before any possible bonuses.
How Much Does LifeMiles Cost
LifeMiles usually costs US$33 per 1,000 miles and with the current promotion, you can receive up to 470,000 miles for US$6,600 which is around 1.4 cents per mile.
This is not considered to be the best buy-miles bonus the program is offering so I would recommend you to buy miles if you have specific travel plans in mind.

Redeeming LifeMiles
The LifeMiles program is one of my favorite airline programs to redeem miles and I frequently use them to redeem on flights. And unlike Aeroplan or MileagePlus, the best feature of this program is that it charges no fuel surcharges when redeeming awards on Star Alliance partners.
Paying US$6,600 for 490,000 miles might be costly but given that there are award sweet spots on some destinations, for example, Asia to Europe in first class costs 102,000 miles or Asia to the US for 99,000 miles, you can book first and business class tickets with a fraction of the regular cost.
The only major disadvantage is that the program is showing phantom awards as well as erroring out when clicking for the flight. So it is best to make a phone call to customer service or chat online to make a reservation.

Summary
Through September 27, 2023, Avianca’s LifeMiles is offering a bonus of up to 135% when buying miles where you can buy miles at 1.4 cents per mile. This offer is not in line with the best bonus rate so if you only have specific travel plans in mind, I would take advantage of the offer.
