Flying San Diego Seoul at the front of the plane
Booked well, San Diego to Seoul in First Class is not an indulgence so much as arithmetic: a flat bed out of San Diego International Airport (SAN), hours of genuine sleep, and a first day in Seoul you don't lose to recovery.
Because no carrier flies true First Class nonstop on this pairing, the routing craft matters. ANA, Japan Airlines and Cathay Pacific each offer superb one-stop itineraries through their hubs, often at fares below what a nonstop business seat would cost, with a lounge stop that feels like part of the vacation.
San Diego has no dedicated First Class lounge, though the British Airways departure uses a comfortable contract facility in Terminal 2. The real ground experience belongs to the return leg, where First passengers get the First Wing fast track and the Concorde Room at Heathrow Terminal 5. Travelers positioning through Los Angeles can use the Qantas First Lounge at LAX on qualifying itineraries.
On timing: 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.
