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.
