Religious tourism: Hajj pilgrimage's key role in bolstering Saudi businesses

With Muslim pilgrims streaming into holy city of Mecca ahead of the start of the Hajj later this week, businesses in Saudi Arabia are set to flourish. Saudi officials said more than 1.5 million foreign pilgrims had arrived in the country by Tuesday, the vast majority by air, from across the world. More are expected, and hundreds of thousands of Saudis and others living in Saudi Arabia will also join them when the pilgrimage officially begins on Friday.
