Air India on Sunday said it will reduce its India-Sri Lanka services from 16 flights per week currently to 13 flights per week from April 9 due to poor demand.

Sri Lanka is currently experiencing its worst economic crisis in history. With long lines for fuel, cooking gas, essentials in short supply and long hours of power cuts, the public has been suffering for weeks.

"Currently AI is operating 16 flights a week -- daily flights from Delhi and nine flights a week from Chennai," an Air India spokesperson told PTI.

In the new schedule, AI will be operating a total of 13 flights per week, the spokesperson noted.

In the new schedule, while the frequency from Chennai will remain untouched, flights from Delhi will reduce from seven to four per week, the spokesperson said.

"Four flights from Delhi instead of seven effective April 9 due to poor loads," the spokesperson noted.

AI 283 on the Delhi-Colombo sector will now operate on Mondays, Wednesdays, Fridays and Sundays from April 8 to May 30.

AI 284 on the Colombo-Delhi sector will operate on Mondays, Tuesdays, Thursdays and Saturdays from April 9 to May 31.

The Sri Lankan government on Sunday blocked social media platforms such as WhatsApp, Twitter, Facebook and Instagram after declaring a nationwide public emergency and imposing a 36-hour curfew ahead of a planned anti-government rally over the worst economic crisis in the island nation.

The move is aimed at preventing masses from gathering in Colombo to protest the government's failure to provide relief to the public suffering from shortages of food, essentials, fuel and medicine amidst hours-long power cuts, the Colombo Page newspaper reported.
