Check-In and Baggage Services
Southwest’s check-in area is located on the Departures Level of Terminal 1. Clearly marked signage makes it easy for passengers to find the appropriate counters. The airline offers:

Self-service kiosks for printing boarding passes and bag tags
Staffed check-in counters for passengers with special needs, checked baggage, or paper tickets
