----------

Until August 31, 2015, you can transfer 20,000 SPG Starpoints to 30,000 American Airlines AAdvantage miles.

Update August 30, 2015: You must book your Hawaiian Airlines awards between the United States mainland and Hawaii by Monday August 31 if you want to use American Airlines

Malaysia Airlines has an incredible First Class product on its A380, on par with the best in the world. I flew Malaysia First Class from Paris to Kuala Lumpur in 2013 and loved the service, luxury touches, and satay cart.

You can fly the same product between London and Kuala Lumpur for 70,000 American Airlines miles with great award availability.

Singapore Airlines charges only 12,500 Singapore miles one way for awards within the Southwest Pacific, which includes Australia, New Zealand, and a bunch of island paradises.

Singapore Airlines', Star Alliance partner Air New Zealand, flies extensively in the region from its hub in Auckland. Here are its flights to tiny islands.

And here is its route network from Australia.

Air New Zealand also has an incredible route network within New Zealand.

Korean Air has multiple award charts when redeeming its SkyPass miles. There is one award chart to fly Korean, one award chart to fly SkyTeam partners, and award charts to fly Alaska, Hawaiian, Gol, and Emirates (click logos). Each award chart has sweetspots, so I will run through all the sweetspots in three posts. The post on Korean Air sweetspots is here. You are reading the second post on sweetspots on the SkyTeam chart.This third post on sweetspots when flying Korean's non-alliance partners is here.

Korean SkyPass miles should have your attention.

Until October 6, 2015, you can buy 56,000 or more Alaska Airlines miles for 2.11 cents each.

The sale is structured as a bonus on the normal number of miles you’d receive. The bonus is tiered, so the biggest 40% bonus comes from purchasing 40,000 miles at the normal price of about 2.96 cents each after tax.

To buy 56,000 miles (40,000 + 16,000 bonus) during this sale costs $1,182.50, which is 2.11 cents per mile. This is not the best sale we've seen.

American Airlines is releasing a ton of First Class award space from Miami and Dallas to Madrid for May through July, 2016.

This award space is easy to connect to from anywhere in the United States, and you can get anywhere in Europe with an Iberia flight from Madrid. These connecting flights do not add to the First Class mileage price of 62,500 American Airlines miles each way.

As of 8 PM ET on August 27, transfers from Ultimate Rewards to Korean are back.

Transfers from Chase Ultimate Rewards to Korean Air SkyPass miles are "temporarily unavailable" according to Chase's website.

The transfers were also temporarily unavailable from November 2014 until January 2015. In that instance, Chase communicated that the problem was temporary and Korean signaled transfers would return in January, which they eventually did.

I've reached out to Chase to see if we can get a timeline on just how temporary this problem will be.
