INDIANS ARE on the move. In 2019 international departures from India hit 27m, a number that will surely be exceeded this year and is predicted to rise to 90m by 2040. Annual spending on foreign travel by Indians will nearly triple to $89bn in three years, reckons Bernstein, a research firm. Airlines’ networks are being expanded and redesigned to handle larger numbers of Indian tourists. Many trips are for business or to visit friends and family. But about 40% are pure leisure, and holidaymakers pack fat wallets.
