The Airports Economic Regulatory Authority (AERA) has reduced passenger fees at Bengaluru’s Kempegowda International Airport for the 2026-2031 period. Domestic departure fees will drop to Rs 300, while new arrival charges are being introduced. The regulator has also implemented an incremental revenue model that links charging passengers to the actual completion of infrastructure projects.
Air travelers flying out of Bengaluru’s Kempegowda International Airport will see a significant reduction in airport user charges starting September 1, 2026. The Airports Economic Regulatory Authority of India (AERA) has ordered a 45% cut in the User Development Fee (UDF) for domestic departing passengers, lowering the rate to Rs 300 from the current Rs 550. This revised structure will remain in effect for the five-year control period ending March 31, 2031.
International departing passengers will also benefit, with their UDF reduced to Rs 997, down from the existing Rs 1,500. Alongside these reductions, AERA has introduced a new fee for arriving passengers, set at Rs 125 for domestic flights and Rs 426 for international arrivals. These changes come after the regulator rejected the higher fee proposals submitted by the airport operator, Bangalore International Airport Ltd (BIAL).
A Shift to Incremental Revenue Framework
Beyond the fee reduction, AERA has introduced a major change in how the airport is allowed to recover costs. Under the new 'incremental Average Revenue Requirement' (ARR) framework, the airport operator can only begin charging passengers for high-value infrastructure projects once those assets are fully completed and operational. Previously, airports could often incorporate costs for upcoming projects into their tariff calculations before construction was finished.
This framework specifically targets major ongoing expansions, such as the Eastern Cross Taxiway and Phase 2 of Terminal 2. The regulator’s move aims to protect passengers from paying for unbuilt infrastructure, effectively shifting the risk of project delays or cost overruns onto the airport operator. If these projects face delays, the impact on tariff recovery will be deferred until the assets are commissioned, which the regulator expects to influence financial calculations starting in the 2029-30 fiscal year.
Financial and Operational Impact
For the operator, the decision represents a tighter regulatory environment. AERA determined a baseline Average Revenue Requirement of Rs 14,604.31 crore for the fourth control period, which is substantially lower than the Rs 41,398.93 crore originally proposed by BIAL. This reduction in the allowed revenue baseline, combined with the new fee structure, may put pressure on the airport’s short-term aeronautical cash flows.
The sector’s focus now shifts to how BIAL manages its capital expenditure programs under this stricter oversight. Because the recovery of costs is now tightly linked to the commissioning of assets, any delays in executing capacity expansion projects could hinder the operator's ability to maintain higher revenue levels. Investors and stakeholders may monitor the progress of upcoming infrastructure milestones and whether the current landing and parking charges—rationalized at Rs 442 per metric tonne for domestic and Rs 652 per metric tonne for international flights—provide sufficient buffer to balance operational costs.
