Colombian air carrier Avianca might not be on your radar, but its loyalty program, LifeMiles, should be. It’s got pretty solid award redemption rates (when you can find ’em) and no fuel surcharges on partner bookings.

The program is a transfer partner of several flexible reward programs, which means your account can be topped off at any time.

LifeMiles uses a region-based award chart, yet still offers opportunities to book awards at promotional rates.

Avianca Partners

Avianca is a Star Alliance member, the largest airline alliance in the world.

Avianca LifeMiles is offering a bonus of up to 145% on purchased miles through November 27, 2017 (this Monday). You'll need to sign into your Avianca account to view the sale. You can buy up to 200,000 LifeMiles during the sale and get up to 290,000 bonus miles (for a max total of 490,000 miles). This is nearly as cheap as it gets. The cheapest I’ve ever seen LifeMiles was 1.32 cents each. But what sets this sale apart and makes it better than past sales is that bonus is not tiered.
