Prince Abdulmohsen Bin Abdulaziz International Airport — Yanbu, Saudi Arabia

Yanbu's airport, formally Prince Abdulmohsen Bin Abdulaziz International Airport and coded YNB, serves a Red Sea port city whose economy rests heavily on petrochemicals and oil export rather than tourism. Yanbu Industrial City, developed under Saudi Arabia's Royal Commission for Jubail and Yanbu, hosts refineries and petrochemical plants that draw engineers, contractors, and business travelers through the terminal. The airport also connects visitors to Yanbu al-Bahr, the restored old town of coral-stone buildings that predates the industrial zone by centuries and once served pilgrims sailing toward Medina. Diving and snorkeling along Yanbu's coral reefs have slowly built a leisure market alongside the industrial traffic, part of a wider push to open Saudi Arabia's Red Sea coast to visitors. Domestic flights link YNB to Jeddah, Riyadh, and other Saudi cities, with limited international service.
