Flying Washington, D.C. Seoul at the front of the plane
Booked well, Washington, D.C. to Seoul in First Class is not an indulgence so much as arithmetic: a flat bed out of Washington Dulles International Airport (IAD), hours of genuine sleep, and a first day in Seoul you don't lose to recovery.
The absence of a nonstop First Class product here is an opportunity in disguise: a one-stop on ANA, Japan Airlines and Cathay Pacific adds a world-class lounge visit mid-journey and frequently prices better than direct premium alternatives.
Dulles offers a solid premium landscape: Lufthansa operates its own lounge complex, and Etihad, Qatar Airways, and Air France premium passengers enjoy dedicated or elevated partner facilities. There is no standalone international First Class lounge, though Lufthansa First travelers receive enhanced handling when the First cabin operates on the Frankfurt route.
April brings cherry blossoms along the Han River and October sets the palaces against fall color, these are Seoul's two perfect months. May, June, and September are close behind. Late June through August is hot, humid, and punctuated by monsoon rain; winter is genuinely cold but crisp, with the city's food culture at its most warming and premium fares at their lowest.
