Bug 453321

SUMMARY
The application shows a drop-down with names of passengers, and you have to switch from one to another to see all the seats. I always have 3 seats in the same coach and it is really annoying to have to do this to see where we should seat.

I understand that for the qr code you cannot show all 3 of them, but it would be better if we could swap right/left between the passengers rather than having to click a precise thing twice (while turning the phone to the controller machine, so the easiers the gesture the better).

But for the seat numbers it would really make more sense to see all of them at once. There is a challenge on how to show this when they are not all on the same coach, and how to map the seats to the names if needed, but that should not be too hard. Maybe put in bold the current coach and seat for the selected name?
