The Big Change: How Much Will You Save?
Starting September 1, 2026, the User Development Fee (UDF) for passengers flying from Kempegowda International Airport (KIA) will be significantly reduced. For domestic departures, the fee will drop by 45%, from ₹550 to ₹300. If you're flying internationally,
the charge is being cut from ₹1,500 to ₹997, a reduction of about 33.5%. This fee is a component of your air ticket price, so the savings will be reflected directly in the final cost of your travel. This change is part of a new tariff order issued by the Airports Economic Regulatory Authority of India (AERA) that will be in effect for the next five years, until March 2031.
A New Fee for Arriving Passengers
While departing passengers will see a welcome reduction, the new tariff structure introduces a UDF for arriving passengers for the first time at Bengaluru airport. Those arriving on a domestic flight will now pay a UDF of ₹125, while international arrivals will be charged ₹426. According to airport operator Bangalore International Airport Ltd (BIAL), this approach of sharing the charge between arriving and departing passengers is consistent with practices at other major Indian airports. Even with this new arrival fee, the combined total for a round trip is lower than the previous departure-only charge. For a domestic traveller, the combined UDF is now ₹425 (₹300 to depart + ₹125 to arrive), compared to the old ₹550. For international travellers, the new combined fee is ₹1,423, which is also less than the previous ₹1,500.
Why the Change? A 'Passenger-First' Approach
The decision to restructure the UDF was made by AERA, the regulatory body that determines airport tariffs. The key reason for the change is the adoption of a new 'incremental' framework for funding airport expansion. In the past, passengers would often pay higher fees to pre-fund large infrastructure projects, regardless of whether they were completed on time. The new model ensures that tariffs to recover costs for major projects—like new terminals or runways—will only be applied after those facilities are actually built, commissioned, and available for use. This new passenger-friendly formula aims to make air travel more affordable and supports the growth of domestic aviation, as domestic travellers make up about 84% of Bengaluru's total passenger traffic.
What Happens in the Future?
The current baseline UDF is set to apply until mid-2029. However, the fee structure is designed to be dynamic. As BIAL completes major expansion projects, incremental charges may be added to the baseline UDF. For instance, projects like the Eastern Connectivity Tunnel and the next phase of Terminal 2 have pre-approved additional charges that will be triggered upon their completion. Looking further ahead, the baseline UDF is scheduled to decrease again from May 1, 2030, to ₹160 for domestic departures and ₹65 for domestic arrivals, before any potential project-linked additions are factored in. This modular approach means that while fees will eventually rise to pay for new infrastructure, passengers will only pay for the facilities as they become operational.
