Seattle International Airport

I rarely enter the United States from Seattle, but at least the Internet at Seattle Airport is free and convenient? (Some countries have airports that are not so convenient) It’s quite novel that you have to collect your luggage before going through customs or transferring flights! I'm pretty sure that both San Francisco and Los Angeles go through customs first and then pick up the luggage. In fact, this might be the first time I went through customs with all the luggage. But my big luggage was stolen yesterday, so this can help me reduce weight for the rest of my trip, right? The photo is a map taken at Seattle International Airport. It is for friends who are in a hurry to transfer. I hope everyone’s luggage will not be stolen (I have talked to the police for an hour)
