One of Delta Airlines SEA Terminal main hubs on the West Coast is Seattle-Tacoma International Airport (SEA), where it predominantly operates from Concourses A and B. To enter the well-equipped concourses, travelers must first check in at one of Delta's designated counters or self-service kiosks before going through security. For a convenient and pleasurable pre-flight experience, travelers will find a range of dining options, shops, and cozy seating areas close to the gates. Passengers who qualify can also unwind in the Delta Sky Club, which provides first-rate facilities and a peaceful setting.
