No they haven’t sold out of child tickets…

Nothing on the child line was clickable.   Spent 10 minutes puzzling and mine-sweeping* the screen to figure out what to do.

This usability boob is on the InterCity coaches online booking site.

The page before this had defaulted to one passenger. On this page I had to

• Reduce the number of adult tickets from 1 down to zero with the green down arrow.
• Then a green up arrow appeared on each of the other rows.

I wonder how many people understand this screen – and how many people give up?

*Jakob Neilsen – usability guru – coined the expression mine-sweeping to describe moving your cursor around a web-page to find anything clickable.
