In addition to the very dense and busy domestic traffic, Saudia focuses on three business areas. Firstly, it is the main airline for travel to/from Saudi Arabia, secondly it profiles itself as an alternative connecting option for flights from Europe/US to Asia or Africa and thirdly it brings Muslim pilgrims to Jeddah, near which Mecca is located.
Saudia has interesting promotions when departing from Milan, Frankfurt or Paris on flights to Africa or Asia. It is best to book flights 2-4 months before departure.
