star alliance

Two world-class airlines, one Tokyo destination, completely different points ecosystems. ANA business class from 100,000 miles. JAL from 55,000 one-way if the saver seat exists. Here is how to find it.

Asiana moved to Terminal 2 at Seoul Incheon in January 2026. All other Star Alliance airlines are still at Terminal 1, which is a 15-minute train ride away. If your flight is operated by Asiana, go to Terminal 2 not Terminal 1. Use your Asiana miles before December 17, 2026. After that date, the programme closes permanently.
