China Eastern flies its 777-300ER with flat beds in Business Class and a flat double bed in First Class for two people to share between several American cities and Shanghai with connections throughout Asia.

You can book Business Class for 77,500 Korean miles or 80,000 Delta miles, and you can book First Class for 100,000 Korean miles. If you book two First Class award seats, you can combine your beds into one large double bed.

I get questions all the time like this:
Hi, I have a million American Express Membership Rewards/Chase Ultimate Rewards/Citi ThankYou Points, what is the best transfer partner to go from [here] to [there.]
There are basically two ways to answer the question:

Look at award charts of all the points' transfer partners and then look for award space using the cheapest miles. I used this method to suggest to my friend that he transfer his Membership Rewards to Flying Blue miles to get from Denver to Tel Aviv.

Delta domestic economy and Delta Comfort+ award tickets are on sale for as little as 5,500 miles one way.

Book by June 7, 2016
Travel August 23 - November 16, 2016 (except September 1 - 8)
Fly one of 8,000 routes on sale (although only a few dozen are listed)

I searched for Columbus to Los Angeles and found the sale price widely available in economy and Comfort+;

It seems that experflyer.com is not accurately displaying Air Tahiti Nui award space that Delta agents can book. Multiple Delta representatives confirmed with me over the phone that four seats in Business Class are available on seven different Air Tahiti Nui flights, all of which show zero award seats in Business Class available on expertflyer.com.
What Air Tahiti Nui Is and Why it Matters
Air Tahiti Nui, headquartered in Papeete, Tahiti, is one of seven airlines that flies into Fa'a'ā International Airport in Tahiti.

Aerolineas Argentinas is cutting its Miami to Cordoba route in June 2016 and its routes from Buenos Aires to New York, Rome, and Barcelona at undisclosed dates according to these (1, 2) Spanish-language articles

Delta is offering discounted flat bed Business Class awards to Europe this summer on select routes. The East Coast and Midwest routes are 105,000 miles + taxes roundtrip. The West Coast routes are 115,000 miles + taxes roundtrip. The normal price is 125,000 miles roundtrip (although I am basing "normal" on the old Delta award charts.

Delta will no longer charge a $25 per passenger fee to book tickets by phone. That's excellent news since some Delta partners like Air Tahiti Nui can't be booked on delta.com.

In February 2015, American Airlines eliminated phone ticketing fees for awards flying airlines that can't be booked on aa.com.

United still has phone ticketing fees for awards--$25 per passenger.

Delta has devalued its miles with no notice (again.)

Effective immediately, awards for travel from November 1, 2016 on are going up in price from the United States to the Middle East in Business Class.
USA to Middle East
Bahrain, Egypt, Iran, Iraq, Israel, Jordan, Kazakhstan, Kuwait, Kyrgyzstan, Lebanon, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, Uzbekistan, Yemen

Is: 40k/70k each way in economy/Business
For Travel October 1 to October 31: 35k/70k
For Travel November 1 on: 35k/85k
Change: 5,000 fewer Delta miles each way in economy to the Middle East starting October 1, 15,000 more miles

Back in January I wrote about Delta's devaluation of awards to Australia, Asia, Africa, and South America effective October 1, 2016.

To give a two sentence summary, a few regions in economy are going down in price, and three regions in Business Class are going up in price.

Awards for travel from October 1, 2016 on are going up in price to:

North Asia in Business Class
Southwest Pacific in Business Class
Africa and South Africa in Business Class

(Did you notice that this is very different than American Airlines' devaluation where the price is determined by the day you
