Lufthansa is offering roundtrip first class flights between Helsinki (HEL) and Seoul, South Korea (GMP) for just $3,370. This itinerary will require travel from Helsinki to Germany, then on to Tokyo, and finally on to Seoul. The HEL to Germany route will be on Lufthansa’s unremarkable A321 business class, but the leg from Germany to Tokyo will be on ANA’s excellent 777-300ER first class. The Tokyo to Seoul leg will be on ANA’s decent 787 business class.
This fare leverages a codeshare with Lufthansa; you can’t book this through ANA without paying over $22,000. You can also get this fare through OTAs like Orbitz and Priceline.
You can book this itinerary starting in November 2020 through March 2021. There’s a maximum stopover of three months.
