When I was going to board, one of the staff members told me that I could not board with my passport bag because it was tree items and I would need to check a bag. This was so stupid ! The bag was small. So I had to put my things in my pockets, put the funny bag inside the other bag. Then go throw it. Then in the plane put everything back again in my funny bag.
