T’way Air will significantly expand its Australian operations this summer, ahead of a rebrand, increasing its Sydney-Seoul service from three weekly flights to daily departures from October.
The additional services will provide Australian travellers with greater flexibility to visit South Korea and connect onwards to T’way Air’s growing international network, which now spans 60 destinations across Asia, Europe, North America and Oceania.
Under the airline’s winter 2026 schedule, running from 25 October 2026 to 27 March 2027, flights will depart Sydney at 12.15pm, arriving in Seoul at 9.15pm local time. Return services will leave Seoul at 9.40pm, landing in Sydney at 10.15am the following day. T’way Air has launched a series of promotional offers for bookings made by 31 August.
Travellers can save up to eight per cent on Economy and Business Class fares using the promo code JUL26. The airline is also offering a AU$30 discount on bookings of AU$500 or more for travel between 1 July 2026 and 27 March 2027, as well as a AU$50 Early Bird coupon on bookings over AU$600 for travel between 1 November 2026 and 27 March 2027.
The increased capacity comes as demand for South Korea continues to grow among Australian travellers, with Seoul attracting visitors for its food scene, shopping, historic palaces and year-round cultural festivals.
The expansion also precedes a major corporate change for the airline. Following shareholder approval and regulatory clearance from South Korea’s Ministry of Land, Infrastructure and Transport, T’way Air is set to rebrand as Trinity Airways Co., Ltd.
The airline said the new brand will officially launch once all remaining domestic and international approvals have been secured. Existing bookings will remain valid throughout the transition, and passengers will not need to take any action.
T’way Air has operated since 2010 and has steadily expanded beyond its low-cost carrier roots, adding long-haul services across Europe, North America and Australia while continuing to strengthen its presence throughout Asia
