Nationwide Delta SkyMiles Sale: Seoul in Delta One Suites from 102K One-Way
Minneapolis (MSP) to Seoul (ICN), Business, One Way.
Fly Delta One Suites — lie-flat seats with closing doors — all the way to Seoul this summer and fall, starting at 120,000 SkyMiles one-way from Minneapolis (nonstop), plus just $6 in taxes. With the 15% Delta Amex award discount that drops to about 102,000 SkyMiles each way. The same A350 suite sells for roughly $3,600 one-way in cash, so you're getting around 3 cents per SkyMile — and these normally run 300K+ miles each way. Dozens of U.S. and Canadian cities are included, with nonstop departures from Minneapolis and Salt Lake City. Book one-way for half the cost of a round-trip, and it's fully refundable. Best availability is July–August, with more dates opening October–November.
Head to delta.com and toggle "Shop with Miles" before you search, so prices show in SkyMiles instead of dollars.
Search one-way from your nearest departure city to Seoul (ICN) on the dates you want. Open "Advanced Search" and set the cabin to "Delta One" to filter for the lie-flat suites.
Use the "Price Calendar" view to see a full month at a glance and spot the lowest-mile dates — summer (July–August) has the widest availability.
For the nonstop A350 suites, filter for "Nonstop" and search from Minneapolis (MSP) or Salt Lake City (SLC).
Transfer Amex Membership Rewards to Delta SkyMiles only after you've found your dates — transfers are 1:1 and usually instant. If you hold a Delta Amex card, the 15% award discount is applied automatically at checkout.
Book one-way for half the cost of a round-trip. To get the lowest return rates, book the round-trip originating in the U.S. — one-way awards departing Seoul price much higher.
