The government is reviewing the 5/20 norms -- whereby only those airlines operating in domestic sectors for at least five years and having a minimum fleet of 20 planes are allowed to fly abroad.
In a written reply to the Rajya Sabha, Minister of State for Civil Aviation Mahesh Sharma said the government is in the process of reviewing eligibility criteria of scheduled carriers for operation on international routes in consultation with stakeholders.
"The same is in the formative stage," he said.
"As per the Winter Schedule 2014-15, Indian carriers were not using bilateral entitlements with about 80 out of 109 countries falling under bilateral tie-ups," the Minister said.
Foreign carriers offer 4,32,456 seats a week for Indian passengers compared to 2,42,365 seats offered by domestic carriers.
