The so-called "halal tourism" market was once seen as a niche revenue stream, limited to pilgrimages. But now there's a movement in the tourism industry to widen the "halal tourism" market to cater to Muslim travelers worldwide, particularly those from wealthy Gulf Arab states. Travelers from Saudi Arabia, Kuwait, Qatar, the United Arab Emirates, Bahrain and Oman will spend $64 billion traveling this year and are expected to spend $216 billion by 2030, according to a 2014 study for the travel tech company Amadeus. The study found that, on average, a traveler from these countries spends around $9,900 per trip outside the Gulf. For Emiratis, the figure reaches $10,400.
