Hello, Special cabin redemptions on Korean Air flights, particularly for business and first class to Asia, are often the best use of korean air miles. Booking partner awards with SkyTeam airlines such as Delta or Air France can also provide excellent value. With Korean Air, you can redeem round-trip tickets that include a stopover, increasing flexibility and value. Another advantage is family mileage pooling, which simplifies the process of combining miles for a group journey. In general, the miles accumulate most on long-haul international flights that are booked ahead of time.
