Spending the night at the airport
Seattle airport operates with numerous flights and connections around the globe, so movement is constant, and it is frequent to find many passengers waiting for their flight departure even through the night. It is recommended to have earplugs or headphones, as there are usually loud announcements, and a sleep mask, as some areas are pretty bright.
Where to rest:
Most seats inside the enclosure have armrests, but there are some long and padded benches, ideal for resting, in concourses A, C and S and between gates B6 and B8. In addition, on the second floor of the terminal there is a meditation room with comfortable seats and a quiet setting, and next to gate B4 there is a rest zone with comfortable seating. Another option (by paying or with a credit card that provides the service) is to use one of the VIP lounges, where you can access more amenities and privacy, although they close at night.
