My trip was temporarily booked, so there were a lot of things that didn’t go through. I could only get to my destination after haneda airport transfer. It was my first time at haneda airport transfer, so there was so much I didn’t understand. I asked the stewardess something about it on the plane. They know a lot about it because there are always some passengers who have such questions so they can help patiently. After I got off the plane, I asked the airport staff to make sure I was going in the right direction, and they were all very enthusiastic about telling me how to change planes. The trip was not very smooth, but it was interesting and they learned a lot of different things.
