According to Kathuria, liberalisation of air services between India and Sri Lanka is an example how countries stand to benefit from such a process.
A book titled ‘A Glass Half Full – The Promise of Regional Trade in South Asia’, which Kathuria has edited, shows that India has the highest number of flights with Sri Lanka at 147 departures and arrivals in a week while only six flights are scheduled between India and Pakistan. In effect, the book has claimed that since 2003, when the first such air service liberalisation happened, there was a steady growth in Sri Lankan tourist arrivals in India and since 2005, India is the biggest source of tourist arrivals in Sri Lanka.
