T'way Air permits passengers traveling in standard economy classes to bring a combined carry-on limit consisting of one cabin bag weighing up to 10 kilograms plus a small personal item like a handbag or laptop case. Checked baggage allowances depend strictly on the selected fare type, ranging from zero allowance on basic promotional tickets to 15 kilograms on smart fares, 20 kilograms on normal tiers, and up to 30 kilograms for business class passengers, with excess baggage incurring heavy fees.
