1-866-829-1086 Southwest Airlines Portland Office
Southwest Airlines doesn't have a separate "office" in Portland, but operates at Portland International Airport (PDX), located at 7000 NE Airport Way, primarily serving passengers from Terminal E, with ticket counters opening about 3 hours before the first flight for ticket/baggage needs. For general customer service or corporate matters, you'd contact them online or via phone, as they're headquartered in Dallas.
