The VIP protocol for airports, developed in 2007, has to be followed by all, including private airlines.
The government today said in Parliament that privileges for Members of Parliament at airports will continue and there has been no proposal to curtail them.
The government's answer to a starred question came amid a national debate about VIPs flaunting and abusing the privileges accorded to them. The special treatment accorded to lawmakers at airports has been drawing mounting criticism.
Explaining the facilities that are being provided lawmakers, civil aviation minister Ashok Gajapati Raju said these include reserved lounge facility at all international and domestic terminals, free water and hot beverages.
Lawmakers are also given free access to terminal building and visitors' gallery; entry pass is provided for their staff in Delhi and their constituencies.
It is mandatory for all airports to designate one officer as "protocol officer" to see that all courtesies and facilities are extended to Parliamentarians.
Lawmakers also act as the chairman of airport advisory committee of airports that come under their constituencies.
The guidelines, developed in 2007, have to be followed by all, including private airlines. Last year, however, many private airlines unofficially refused to follow the guidelines and since then, many lawmakers have repeatedly complained about non-cooperation and discourtesy from them.
But cutting across party lines, many politicians have also condemned the VIP culture.
Former Jammu and Kashmir chief minister Omar Abdullah had criticised the system, saying the special treatment reflected a special kind of disconnect with reality. Congress leader Sanjay Nirupam had said he did not support it.
This year, Arvind Kejriwal's two-year-old Aam Aadmi Party won widespread support for its commitment to uproot VIP culture in Delhi.
