Why are US airports introducing outdoor lounge terrace experiences?

US airports are rapidly evolving into experiential travel hubs as airlines and airport operators compete to redefine premium passenger comfort. According to aviation industry insights and airport development reports, travellers now expect more than traditional indoor lounges, leading to a global shift toward outdoor terraces, open-air seating, and wellness-oriented airport environments.
