With this, India now has such pacts with 28 countries, including Afghanistan, Bahrain, Canada, France, Germany, Iraq, Japan, the Maldives, Nigeria, Qatar, the UAE, the UK and the USA.
Under an air bubble pact between two countries, special international passenger flights can be operated by their airlines into each other's territories under restrictive conditions.
"India has finalized an air bubble agreement with Sri Lanka, making it the 6th such arrangement in SAARC region and the 28th in total," the Civil Aviation Ministry said on Twitter.
"All the eligible passengers will be able to travel between the 2 countries in the near future," it noted.
Scheduled international flights have been suspended in India since March 23, 2020 due to the coronavirus pandemic.
However, special international passenger flights have been operating under the Vande Bharat Mission since May last year and under bilateral air bubble arrangements since July.
