Seoul → Los Angeles
A very long flight from South Korea to United States. The clock rolls back 16 hours when you land.
You'll cross the International Date Line and the calendar rolls back a day at the crossing.
A megacity on the Han River
Seoul is a dense, mountainous megacity split by the Han River, with the historic core and palaces to the north and newer business districts like Gangnam to the south. It runs on a fast, cheap, and far-reaching subway system, so a car is rarely needed. The metro area is vast and packed, ringed by hills and high-rise housing. Its main airport sits on an island well west of the city, a fair distance out.

The Entertainment Capital of the World
Los Angeles is a spread-out city in a much larger county, with the Pacific on one side and mountains on the other. The places travelers usually mean by "LA" can be far apart: beach cities, studio districts, downtown, canyon neighborhoods, museum corridors, and the San Fernando Valley. The region is built around driving, and a short distance on the map can become a long trip in traffic. Where you stay matters more here than in most cities, because crossing the basin can shape the day.
City access
LAX sits on the coast at the western edge of the basin, handy for the beaches and the Westside but a long way from downtown, Hollywood, or the Valley. Transit to the airport is limited and slow, so most travelers leave by car, ride-hail, or shuttle. Factor the drive into your timing, because from the eastern and northern suburbs it can be one of the longest legs of the trip.

Small updates, route observations, and clearer explanations for how the app keeps evolving.
Type less, wait less, wonder more
Airport search now understands metro codes and old city names, FlightSide loads noticeably faster, and a new Feeling lucky button chooses a flight for anyone without one in mind.
A closer look at the route, not just the seat

It's all about the sun (after all)
Not all sunlight reaches the side windows. FlightSide now weighs the sun’s angle to the cabin and shows twilight along the route.
