Book Delta One award availability to Seoul this summer
Delta is currently showing plentiful award availability in Delta One, its business-class suites, from the East Coast to Seoul in July and August. We found flights from New York, Boston, Miami and Washington, D.C., for just 135,000 SkyMiles and $6 one-way. Atlanta to Seoul is even cheaper at 130,000 miles and $6 one-way.
You can fly into one of Seoul's two international airports: Incheon International Airport (ICN) or Gimpo International Airport (GMP). It's easiest to search all Seoul-area airports by typing "SEL" into the destination box.

To check availability across an entire month, tick the "My dates are flexible" box when you begin your search, then click "Price calendar." Be sure to also check the "Shop with miles" box and select Delta One in the fare drop-down menu.
If you're not located on the East Coast, don't feel left out. We found Delta One award availability to Seoul from Dallas, Chicago, Denver and Los Angeles for the same price. Or, if you're not near one of these hubs, you might consider booking a positioning flight.
Plus, if you hold a Delta cobranded credit card, you'll get a 15% discount on Delta-operated award flights (not including taxes and fees); this means you could pay fewer than 115,000 miles one-way.
Delta One is a fully enclosed suite in the sky with sliding doors and do-not-disturb indicators. These seats provide extra privacy along with the usual business-class perks, including lie-flat seats, gourmet food, lounge access and more. Delta One seats on long-haul flights can often go for hundreds of thousands of miles each way. So, 130,000 is a great deal.
While getting to Seoul in Delta One is a steal, coming home is a different story. Award availability from Seoul to the East Coast is currently hovering around 400,000 miles for Delta One (or 135,000 if you downgrade to economy class).
In this case, it's worth searching for your return flight on other airlines and credit card travel portals to find the best rate, in either points or cash.
