Phoenix Sky Harbor International Airport (PHX), often referred to as "America's Friendliest Airport," serves as a significant hub for Southwest Airlines. The airline's presence in Terminal 4 has evolved over the years, culminating in the opening of the new South 1 (S1) concourse in June 2022. This expansion not only enhances Southwest's operational capacity but also introduces a range of passenger amenities, sustainability features, and artistic installations.​ https://airlinesofficesworld.com/southwest-airlines-phx-terminal-phoenix-sky-harbor-international-airport/
