<h1>Delhi Airport Hikes International Passenger Fees from April 16; Domestic Charges Unchanged, AERA Approves 140% Increase</h1> International passengers at Delhi airport will face higher user development fees (UDF) starting April 16, as approved by the Airports Economic Regulatory Authority (AERA). The UDF for domestic passengers remains unchanged at Rs 129. International economy class passengers will pay Rs 650 for departure and Rs 275 for arrival, while business class passengers will pay Rs 810 and Rs 345, respectively. AERA rejected a proposed 730% increase in airport charges, opting for a 140% rise to support capital expenditure and service quality. The changes reflect the 'user pays' principle and aim to maintain operational efficiency.
