The decision was taken at a meeting of the Indian airlines called by the government here today.
"The airlines sought some more time to file their response to the issue at the meeting. They have been given time for one more week to do so," a ministry official said.
The meeting was attended by all seven domestic carriers - Air India, Jet Airways, GoAir, IndiGo, SpiceJet, AirAsia India and Vistara.
Recently, the government had proposed to replace the 5/20 rule which makes it mandatory for airlines to have five years of domestic operations and a 20 aircraft fleet to become eligible for flying international.

It may be noted here that the Federation of Indian Airlines (FIA), the umbrella organisation of the local carriers, is vehemently opposed to the proposed relaxations and wants the government to continue with the existing policy.
While Air India has opted out of the FIA, AirAsia India and Vistara are not a part of the Federation.
The government wants to finalise the policy by mid-February.
Further the RDGs require to evolve into a viability gap funding (VGF) model, rather than becoming a larger constraint on the airlines of India, so that the airline industry can deliver greater socio-economic impact where it is required and moves towards viability, it said.
Also it should ensure that the responsibility for domestic connectivity is equitably shared by all airlines as well as other important industry stakeholders, the letter said.
