We were coming from LAX (Los Angeles, California) to the Narita Airport in Japan. (We stopped here first, then went to Incheon, South Korea.) They have a lot of security checks! This was before the ban on liquids on airline flights, so it was a bit of a hassle. My mom and I probably went through five, that I can remember off the top of my head, checkpoints before we made it to the resting area.
