SINGAPORE – Escalating tensions between Iran and the United States have rippled through the global travel industry, raising the prospect of longer flight routes, higher airfares and shifting holiday plans. 

For travellers in Singapore, the conflict has added a new layer of uncertainty to long-haul trips, particularly those passing through Middle Eastern airspace. More than 52,000 flights have been cancelled since the war began on Feb 28, according to aviation data provider Cirium as at March 13.
