I just booked myself an award from Los Angeles to Santiago, Chile in Business Class for 35,000 Asiana miles + $24. United would have charged 55,000 miles for the same flights!

Why Asiana Miles
Asiana has really cheap awards to Europe and South America and really expensive awards elsewhere.

Turkish Business Class flat bed award space is wide open to Europe, Africa, the Middle East, and Indian Subcontinent for Summer 2016. You can book award space for 2-8 people in Business Class on routes from America to Turkey and beyond with United miles, LifeMiles, Aeroplan miles, Asiana miles, and many other Star Alliance miles.
Where Turkish Flies
Turkish will soon fly from nine American cities to Istanbul.

From Istanbul, you can connect to over 100 countries.

To anyone who will listen, I say that you should not expect to use your miles at peak times on high demand routes. Airlines use miles to get rid of distressed inventory--seats they don't expect to sell.

A few weeks ago, I used 27,500 Asiana miles (transferred from 22,500 Starpoints) to book myself a Business Class award from Honolulu to Bogota, Colombia. Now I'll tell you how to change an Asiana Club award.

I chose to use Asiana miles because it has a number of ridiculously cheap sweet spots including from Hawaii to South America.

Last week I used 27,500 Asiana miles + $38.30 to book myself a Business Class award from Honolulu to Bogota that I'll fly next month.

This is a steal of a deal because United would have charged 45,000 miles for the same ticket.

While I am ticketed, one of my two legs is in economy, so I have set an automatic alert to let me know if Business Class space opens on the leg on which I'm currently ticketed in economy.

United is offering tons of Business Class award space for the next 11 months on its flights to Rio de Janeiro, Brazil and Santiago, Chile.

Both routes will soon be flown by United's brand new 787-9 Dreamliners with flat beds in Business Class. You can book either route for as little as 35,000 miles one way.
United 787-9 Dreamliner
The United 787-9 Dreamliner has 48 beds in Business class in a 2-2-2 configuration. I would choose a middle seat, since both have direct aisle access.

Updated June 3: The Asiana miles showed up today, meaning the transfer took 14 days. My last transfer in September 2014 took 17 days. In the interim, I've decided not to book Lufthansa First Class from Europe to the United States in June, but the Asiana award chart is so good that I don't mind have 60,000 points on hand. That's almost enough for Business Class one way USA to Argentina (35k) + First Class USA to Hawaii (27.5k).

You can book Lufthansa First Class for 50,000 Asiana Club miles--40,000 Starpoints--one way.
