2. Why Choose South Korea Airlines for Asia Travel

4. Comparing South Korea Airlines: Key Decision Factors
Each traveler’s needs differ. Before booking, weigh these essential considerations:

LCCs: Cheaper base fares, but extras like meals, seat selection, and baggage come at an additional cost.
FSCs: All-inclusive fares typically include checked baggage, meals, and a variety of in-flight entertainment options. - Frequent Flyer Programs
FSCs like Korean Air (SkyTeam) and Asiana Airlines (Star Alliance) allow you to earn miles on partnered airlines. If loyalty perks matter, consider these alliances.
LCCs generally don’t have robust mileage programs, though some do offer basic point-accumulation systems. - Route Networks
LCCs shine for domestic and short regional flights, while FSCs cover long-haul, intercontinental routes with more frequency.
If you’re planning a transpacific or intercontinental journey, going with a full-service carrier often means more flexible schedules and better connections. - Airport Convenience
Seoul has two major airports: Gimpo (GMP) for mostly domestic and short-haul flights, and Incheon (ICN) for international routes.
Busan (PUS/Gimhae) is a convenient hub for travelers in the southern regions of South Korea.
