Sea‑Tac Airport offers a variety of lounges — more than at many U.S. airports — spread across the Central Terminal, A, C, D, N (North Satellite), and S (South Satellite) areas. Depending on your airline, ticket class, elite status, or lounge membership, you may have access to one or more of these spaces.

- Alaska Lounge – Three locations in Concourse C, Concourse N, and Concourse D
- British Airways Terraces Lounge – Concourse S (for Oneworld carriers and eligible passengers)
