<h1>Delhi Airport Tariff Hike Could Increase Domestic Airfares by 1.5-2% Pending Regulatory Approval</h1> A proposed tariff hike at Delhi's Indira Gandhi International Airport by Delhi International Airport Ltd (DIAL) will lead to a 1.5-2% increase in domestic airfares. The new tariffs, pending approval from the Airport Economic Regulatory Authority, will raise the Yield Per Passenger from Rs 145 to Rs 370, with a significant shift in cost distribution towards passenger charges. DIAL plans to upgrade facilities, including shutting down Terminal 2 temporarily for improvements. The Association of Private Airport Operators supports the variable tariff model, emphasizing affordability and financial viability. DIAL has invested heavily since 2006, despite accumulated losses.
