Discover Can You Choose Seats on Japan Airlines? You may add a personal touch to your journey by selecting your seat when you purchase your flight or check in. You may easily locate the ideal seat with the help of their user-friendly mobile app and website. I like that there were a variety of options to suit varied tastes, such as window seats and additional legroom. Japan Airlines is a fantastic option for passengers since it allows you to select your seat, which makes your trip more comfortable and less stressful. Strongly advised.
