T'way Air
A South Korean low-cost carrier linking Seoul and Jeju with regional Asian destinations, using a predominantly Boeing fleet and an unbundled fare model.
About T'way Air
T'way Air is a South Korean low-cost airline whose roots extend to Hansung Airlines, founded in 2004. Operations under the T'way identity began in 2010. Its legal name is T'way Airlines, and it forms part of the T'way Holdings group. The carrier positions itself around affordable, independently selected travel options rather than the bundled service associated with traditional network airlines.
Seoul is T'way Air's primary hub and busiest departure point, with operations also departing from Bangkok, Jeju, Fukuoka and Taipei. The airline operates eight routes serving five destinations across four countries. This network connects South Korea with important leisure and commercial markets in Thailand, Japan and Taiwan, while Jeju provides a major domestic destination within South Korea.
Boeing 737 aircraft are central to T'way Air's recorded operations and are well suited to domestic and short-to-medium-haul regional flying. Service follows a low-cost format, with economy seating forming the core product. Fare conditions determine which extras are included, while checked baggage, preferred seats, meals and other optional services may require advance purchase or a higher fare category.
T'way Air is not a member of Star Alliance, SkyTeam or Oneworld, so passengers should not expect alliance-wide mileage earning, lounge access or through-ticket benefits. The airline does not have a conventional global frequent-flyer programme comparable with those of large full-service carriers. Travellers should instead review the current membership benefits and promotions offered directly through T'way Air's website.
The airline's principal strength is its straightforward low-cost access between South Korea and nearby Asian markets, including useful links among Seoul, Bangkok, Fukuoka, Jeju and Taipei. The trade-off is that the final trip cost can rise once baggage, seat selection, meals or flexibility are added. Passengers connecting from another airline should also allow ample time because separate tickets may not provide protection after a delay.
Good to know
Flying with T'way Air — what to expect
Check Fare Inclusions
T'way Air uses an unbundled low-cost model, so baggage, seat selection and other extras depend on the fare purchased. Compare the total price after adding the services you need.
Prebook Checked Baggage
Buying checked baggage before departure is generally more convenient than arranging it at the airport. Confirm the allowance shown on your booking because rules can vary by fare and route.
Plan Seoul Connections
Check which Seoul airport appears on your ticket, as the metropolitan area has more than one major airport. Allow substantial transfer time if separate bookings require an airport change or baggage recheck.
Meals May Cost Extra
Do not assume a complimentary meal is included on a low-cost fare. Review the flight's catering options in advance, particularly on the longer Bangkok–Seoul sector.
Protect Separate Tickets
T'way Air flights combined with another airline on separate reservations may not include missed-connection protection. Leave a generous buffer and verify whether checked bags must be collected and rechecked.
