We applied a bunch of quantitative and qualitative filters to arrive at this list of 50 cities. First, we looked at data from the Indian aviation regulator to identify the busiest foreign routes from India. Next, we collated data for these 50 cities on 25 metrics that are essential considerations in an overseas travel experience. The cost data was in local currencies, which we converted into dollars, and then rupees. Or, Bali has an index value of 92, which means the same 25 items cost 8% less than in Delhi.
