Starting on January 1, 2014, you can earn Avianca LifeMiles for your stays at InterContinental Hotels Group hotels.
The number of miles that you earn is dependent of the folio amount converted to USD. You earn flat 500 miles per stay at InterContinental hotels outside of the United States + the InterContinental Alliance hotels in the US. At other IHG brands, you earn 2 miles per USD charges.
You can also convert IHG Rewards Club points to Avianca LifeMiles at 10,000 points to 2,000 miles ratio.
Note that the information on Avianca’s website is incorrect. I have crossed over the word “group”.
Barring any promotions for double/triple/quadruple miles, I would continue earning IHG Rewards Club points combined with all the promotions instead of airline miles for stays at IHG affiliated hotels. You can always convert the points to miles at the same ratio late at later time.
