Demand for domestic traffic rose 5.1 per cent, outpacing international demand growth of 4.3 per cent in May 2016 according to the data released by International Air Traffic Association (IATA).
As against this India's domestic air traffic grew 21 per cent, it said.
The overall traffic growth (domestic and international), however, rose 4.6 per cent in May this year over May 2015 with the demand getting impacted due to recent terrorist strikes and UK's decision to opt out of the European Union.
India, which is the fastest growing aviation market currently, had logged 21.8 per cent growth in domestic traffic in April, 2016.
For Asia-Pacific carriers, the large markets in India, China and Japan mean that domestic travel accounts for 45 per cent of the region's operations, IATA said.
Significantly, India accounts for only 1.2 per cent of the total domestic air traffic.
"The shockwaves of the Brexit vote have extended worldwide and the fallout will affect the air transport industry, from both economic and regulatory perspectives," Tyler said.
Traffic growth is projected to slowdown to 5.1 per cent
in 2017 from 5.9 per cent this year as the demand stimulus from lower oil prices taper off next year, it added.
Airlines in the Asia-Pacific region are expected to generate a net profit of USD 6.3 billion in 2017, lower than USD 7.3 billion in 2016.
In 2017, airlines are expected to take delivery of some 1,700 new aircraft and around half of them would be replace older and less fuel-efficient aircraft.
Observing that governments do not make aviation's work easy, de Juniac said the global tax bill has ballooned to USD 123 billion. "Over 60 per cent of countries put visa barriers in the way of travel and the total number of ticket taxes exceeds 230," he noted.
Emphasising that the activities of the aviation industry must be sustainable, de Juniac said it is a challenge for an industry that is carbon-intensive and growing to meet demand.
