Seat selection is a nightmare for travelers. Few airlines allow seat selection/modification at the time of check-in. Few allow travelers to select seats on the date of departure. Few disable this setting. Travelers cannot know which airline/app has configured which setting.

If you are lucky, you might get to choose your seat. During the process, you will see many icons as shown above, with no understanding of what they mean. Until, you find the 'i' icon or the 'Legend' icon, if you are lucky. Once you find it, you have to learn it, close this pop-up and then select the seats accordingly.

Isn't this cognitive load unnecessary? What do you think?
