In this blog, “Future Atlas by Ron,” I write realistic travel diaries of the places I have visited based on my experience of traveling to more than 15 countries, as well as my impressions and insights from my travels.
I usually travel on my days off while working full time in Tokyo, and I am active in my efforts to share the charm of international travel with everyone.
In this article, based on my experience traveling from Haneda to Guam on United Airlines, I have compiled a detailed report on preparations leading up to boarding, what it was like on board, and what I found useful to use.
If you are planning a trip to Guam, please refer to the check-in process, in-flight service, and list of things to bring.
