South Korean low‑cost airlines are cutting prices for flights to Vietnam, Thailand, Malaysia and the Philippines. This article shows what the discounts mean for travelers who want to visit these countries.

Jeju Air says its February flights from Incheon and Busan have discounts of up to 77 percent. Trinity Airways, formerly T'way Air, is also lowering Southeast Asian fares by 22 percent for travel through January. The cheapest base fare shown is 10,000 won from Incheon to Da Nang and 15,000 won from Incheon to Nha Trang.

However, fuel surcharges and airport fees can add between 110,000 and 190,000 won each way. Extra baggage and meals also cost more. Airlines say they cut prices to fill seats and keep their operating rights and airport slots.

Travelers should add the extra fees to the low base price to see the true cost of a trip. A cheap ticket does not always mean a cheap total price.
