Southwest Airlines is known across the United States for its budget-friendly fares, no-frills service, and free checked bag policy. At San Francisco International Airport (SFO), one of the busiest and most iconic airports on the West Coast, Southwest operates exclusively from Terminal 1, also known as the Harvey Milk Terminal 1. This terminal represents a perfect balance between form and function — offering modern amenities, aesthetic appeal, and seamless services that enhance the travel experience for all Southwest passengers.

Whether you’re heading out on a quick business trip, beginning a vacation, or connecting through the Bay Area, this comprehensive guide to the Southwest Airlines SFO Terminal will walk you through everything you need to know — from check-in and security to dining, shopping, boarding, and transportation options.

Terminal 1 at SFO was recently renamed in honor of civil rights icon Harvey Milk, and it has undergone an extensive multi-year renovation aimed at delivering an ultra-modern, sustainable, and passenger-focused travel experience. Southwest Airlines is the anchor tenant of Boarding Area B, located within Terminal 1.

This terminal is designed with a strong focus on:

• Sustainability and energy efficiency
• Intuitive navigation
• Artistic design and local culture
• Enhanced accessibility and comfort

For travelers flying Southwest, this terminal offers not just convenience, but also a touch of San Francisco’s progressive spirit.

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
• Mobile check-in options via the Southwest app for a contactless experience

Southwest allows two free checked bags per passenger — a unique perk among U.S. airlines — and this is well-facilitated at SFO, where efficient baggage services ensure quick drop-off and minimal wait times.

Security Screening at Terminal 1

After check-in, passengers proceed to TSA security checkpoints, which are typically efficient, especially with the modernized infrastructure in Terminal 1. TSA PreCheck is available for eligible travelers, offering faster lines and fewer security protocols (like removing shoes or laptops).

Security lines tend to move quickly, even during busy times, thanks to ample staffing and well-planned queueing systems.

Once past security, passengers enter Boarding Area B, which serves all Southwest Airlines flights. This part of Terminal 1 is where Southwest travelers will spend most of their time before boarding, and it’s filled with amenities that make waiting more enjoyable.

• Floor-to-ceiling windows with panoramic views of the tarmac and Bay Area skyline

The concourse is designed to minimize crowding, even during peak travel hours. Additionally, SFO’s staff is known for being courteous and helpful, contributing to a more pleasant terminal experience.
