Delhi's Indira Gandhi International (IGI) Airport will get India's first inter-state multi-modal transport hub near Aerocity. A proposal has been floated to construct a hub near the GMR Aerocity at the Delhi airport, which will be the confluence point of an Interstate Bus Terminal (ISBT), the upcoming Phase 4 line of the Delhi Metro, the proposed Passenger Transport Center (PTC) and RRTS station, and a station for the Automated Passenger Mover (APM) near Aerocity. The proposal will provide linkage between buses, metro lines, the proposed air train (which will ply between terminals) and of course the airport.

As per the proposal, an Inter State Bus Terminal (ISBT) at the passenger hub, which will be developed in a phased manner in consultation with the Transport Department of the Delhi Government, would handle around 50 buses.

 As per proposal, this transit hub will provide seamless connectivity to the airport through metro, bus and trains to passengers coming from the neighbouring states. Currently, there is no proper facility for parking these interstate buses at Delhi Airport. Therefore, this proposed facility will immensely help all the passengers coming from adjoining interstate cities to catch international flights.

With IGIA's capacity going to cross 11 crore passengers per annum next February and cross 13.5 crore latest by 2032, the sheer volume of footfalls requires this kind of connectivity between the airport and other modes of transport. Delhi Airport, being the national capital's airport and connected to a maximum number of international destinations and airlines, has large catchment areas from Punjab, Haryana, Rajasthan, Himachal Pradesh, Uttar Pradesh, and Uttarakhand. Passengers from these states travel to IGI airport by interstate buses to catch international flights.

According to GMR Airport Infrastructure Limited-operated Delhi Airport , the ISBT, to be developed in consultation with the Delhi Transport Department, will help in bringing long-distance passengers to the airport from the adjoining hinterland. Its location offers the best intermodal connectivity, efficient circulation, and well-laid subway connections for pedestrian movement.

 The proposed airport ISBT will have state-of-the-art passenger amenities, matching the airport standards. It will have the best possible user facilities like retail, F&B outlets, EV charging, transit facilities, comfortable waiting areas, ambience, waiting hall, business centre, internet/Wi-Fi services, souvenir shops, etc. so that passengers, meeters and greeters can avail of these facilities.

 Talking about the development, Videh Kumar Jaipuriar, CEO, DIAL - a GMR Airport Infrastructure Limited-led consortium said, "India's first multimodal transport hub, which will integrate bus, metro, and air services, is a transformative project that redefines passenger convenience, offering enhanced facilities for bus travellers. It will offer an unparalleled passenger experience that begins before you even reach the airport. By prioritizing bus travellers and their needs, DIAL is creating a truly inclusive transportation ecosystem. More than just a transportation hub, this project represents our commitment to sustainable development and reduced traffic congestion. By encouraging public transport usage, DIAL is paving the way for a cleaner, greener future."
