Tway Air

Tway Airlines (ICAO: TWB) is a South Korean low-cost carrier that has grown significantly since its rebranding, expanding its network across Asia, Europe, and North America.

T'way Air's origins trace back to Hansung Airlines, established in 2005. After facing financial difficulties and suspending operations, the airline was reorganized and relaunched as T'way Air on August 8, 2010, starting with two Boeing 737-800 aircraft. Initially, it focused on domestic routes, commencing services between Gimpo International Airport and Jeju International Airport in South Korea.

The airline's main operational bases are Incheon International Airport for long-haul international flights and Gimpo International Airport for domestic short-haul operations. It also utilizes Daegu International Airport as a secondary hub, having relocated its headquarters to Daegu in 2022. As of November 2025, T'way Air operates a diverse fleet of 45 aircraft, including six Airbus A330-200s, four Airbus A330-300s, 26 Boeing 737-800s, five Boeing 737 MAX 8s, and two Boeing 777-300ERs. Future plans include increasing its Boeing 737 MAX 8 fleet to 20 by late 2027 and adding five Airbus A330-900neos in 2026.

T'way Air's route network encompasses both domestic flights within South Korea and international services to approximately 40 destinations across 23 countries. Its international reach extends to Japan, China, Southeast Asia, Guam, Australia (Sydney), and several European cities such as Frankfurt, Paris, Barcelona, and Rome. In July 2025, the airline launched its inaugural North American route to Vancouver, with plans for further expansion to Los Angeles, Seattle, and San Francisco. T'way Air is not currently a member of any major airline alliance like Star Alliance, SkyTeam, or Oneworld, although it is reportedly exploring the possibility of joining Star Alliance. As a low-cost carrier, T'way Air traditionally offered only Economy Class. However, with the introduction of its wide-body Airbus A330s and Boeing 777-300ERs, it now features a Business Class with angle-flat beds on some routes and Premium Economy on its Boeing 777-300ERs. Economy Class seats are typically arranged in a 3-3 configuration on Boeing 737s and 2-4-2 on A330s. In-flight meals and duty-free shopping are available for purchase on international flights, with pre-order meal options.
