Ministry of Civil Aviation (MoCA) launched the Regional Connectivity Scheme Ude Desh ka Aam Nagrik (RCS-UDAN) on 21.10.2016 to enhance 

regional air connectivity from unserved and underserved airports in the country and make air travel affordable to the masses.

Under this scheme, with a view to strengthen tourism connectivity, 53 Tourism RCS routes across the country including North Eastern Region (NER) and Southern India are operationalised under Tourism - RCS (TRCS). 

These routes were funded with 100% Viability Gap Funding (VGF) reimbursement by Ministry of Tourism providing direct air connectivity to tourist destinations and cultural sites in the country. Though

there is no direct air connectivity under RCS Udan between airports at North-Eastern region to Southern Indian airports, indirect connectivity is available through connecting flights.

A total of 90 routes has been operationalised in the North Eastern Region (NER) under the Regional Connectivity Scheme (RCS-UDAN), connecting 10 airports and 02 heliports across the NER states.

Indian Railway Catering and Tourism Corporation (IRCTC) has informed that total 17 trips of Bharat Gaurav Trains on theme-based circuit were operated in financial year 2024-25 in which 9,246 tourists visited Tamil Nadu.
