What Stands Out in the Route Lineup
Kansai offers the widest choice: alongside Busan, Seoul/Incheon and Daegu, it includes Cheongju, which has limited nonstop service from Japan, plus the resort destination of Jeju. Beyond Korea, the Guam route is also included, putting a tropical getaway within reach at 36,016 yen one way all-in. From Narita, Busan is the cheapest at 17,785 yen, followed by Seoul/Incheon and Daegu. From Sapporo/Chitose, travelers can fly nonstop to Busan for 25,450 yen or Seoul/Incheon for 29,250 yen.
Rough Round-Trip Estimates
Simply doubling the one-way all-in fares gives 35,570 yen for Tokyo/Narita-Busan, 38,360 yen for Seoul/Incheon and 42,320 yen for Daegu. From Osaka/Kansai: Busan 36,310 yen, Seoul/Incheon and Daegu 36,510 yen each, Cheongju 36,610 yen, Jeju 47,060 yen and Guam 72,032 yen. From Sapporo/Chitose: Busan 50,900 yen and Seoul/Incheon 58,500 yen. These figures are straightforward calculations based on the lowest one-way fares; actual round-trip pricing varies by flight, travel date and seat availability.
Booking Notes
- Seats are limited in number and the offer ends once the allocation sells out
- Certain blackout dates where the discount code cannot be used are set by route and travel date
- Travel periods differ by route, so confirm eligible dates before booking
- Only the airfare portion is discounted; fuel surcharges and airport facility charges are not
- Event fares are excluded
- Only itineraries departing Japan and booked on the official website qualify
As with most low-cost carriers, seat selection, checked baggage and inflight meals are charged separately, so the final amount paid will exceed the advertised all-in fare once options are added. Compare total prices while factoring in the extras you actually need. Peak periods such as year-end holidays and long weekends may fall on blackout dates, so travelers with flexible schedules stand to benefit the most.
Summary
The t’gal sale is a limited-time, website-exclusive campaign running through August 31 and covering Japan-Korea routes plus Guam. With a travel window stretching to March 27, 2027, it fits autumn long weekends and winter trips alike. Since inventory is capped, booking early is the safer move if your route and dates are already set.
