India has always been a significant source of tourism for Sri Lanka. While Colombo has direct air connectivity with several Indian cities, another destination in the country is set to receive daily service from India – Jaffna. Alliance Air began flying between Chennai in India to Jaffna in North Sri Lanka four times a week last year, and soon, it will increase this frequency to a daily service. Alliance Air will expand its four-times-a-week flight from Chennai in South India to Jaffna in North Sri Lanka into a daily service from July 16th.
