For the first time, the airport tariff regulator has applied a new formula at Bengaluru airport, cutting the passenger fee by 33% from ₹450 to ₹300 and ensuring travellers pay only for commissioned infrastructure available for employ, rather than substantial projects such as runways and passenger buildings to be built going forward.

On August 20, 2026, the Airports Economic Regulatory Authority (AERA) issued the tariff order for Bengaluru's Kempegowda International Airport's fourth five-year tariff cycle, setting the charges payable by airlines and passengers to recover the airport's capital expenditure. The tariff order will come into effect on September 1, 2026 and will be applicable until March, 2031.

Passengers departing from Bengaluru airport will now pay a User Development Fee (UDF) of ₹300, down from ₹550 earlier. Passengers arriving at the airport will pay ₹125. International passengers departing from the airport will pay Rs 997, and those landing will pay Rs 426. The fee for disembarking passengers is being introduced at Bengaluru in line with tariff orders for other airports. Bengaluru's proposal before AERA suggested a UDF of ₹450. This fee is a component of airfares collected by airlines. Further, landing charges levied on airlines that additionally impact airfares have additionally been rationalised.

It additionally ensures there is no over-recovery and incentivises airports to implement their projects in a timely manner and avoid delays, he went on. A similar tariff plan is projected to be ordered by the authority for Hyderabad airport as well.

For context, the new formula means that while Bengaluru airport had cited an Aggregate Revenue Requirement (ARR) of ₹41, 393.8 crore for cost recovery, the new baseline has been set at ₹14, 604.31 crore, resulting in a baseline UDF of ₹390, according to AERA.

During consultations, airports triggered concern that the new approach could affect their cash flows and result in a tariff shock when costs are recovered over a shorter period rather than spread throughout the five-year tariff cycle. AERA, nevertheless, stated it would take the risk of such tariff spikes into account while implementing the new formula.

Airlines that additionally pay landing and parking charges to the airports have welcomed the new move, and the International Air Transport Association (IATA) has expressed its backing and stated that "it is important that the timing of cost recovery remains linked to the point at which users can derive actual benefit from the infrastructure being funded". It has continued that this was additionally in line with tariff regimes in Europe, including the UK.
