Massive hike in user fee at Delhi and Mumbai Airports
Passengers at Delhi and Mumbai airports face significantly higher user charges. A TDSAT order redefines tariff calculations, leading to a potential 22-fold surge. This could increase ticket prices substantially. The Airports Economic Regulatory Au...
In its order, the tribunal redefined the formula for calculating tariffs for the five-year period between FY09 and FY14, which has resulted in a situation where the two airports are now owed an amount of over Rs 50,000 crore, due to under recovery in those years. The amount is to be collected in the form of passenger fees, landing and parking charges that are likely to end up making tickets more expensive, seen hindering passenger growth.
The order has been challenged in the Supreme Court by the Airports Economic Regulatory Authority (AERA), domestic airlines as well as foreign ones such as Lufthansa, Air France and Gulf Air. The case will be heard by a bench of justices Aravind Kumar and Nilay Vipinchandra Anjaria on Wednesday.

People aware of the development said that if the order is implemented, user development fee (UDF) levied on domestic passengers at Delhi airport may increase to Rs 1,261 from Rs 129, and that for international passengers to Rs 6,356 from Rs 650. At Mumbai airport, this could rise to Rs 3,856 from Rs 175 for domestic passengers.
Passengers will be hit hard
It would be Rs 13,495 from Rs 615 for international flyers in the financial capital.Government officials are worried such a sharp increase in charges will hit passenger growth.
“Irrespective of the merits of the order, passengers shouldn’t become victims of protracted legal battles between airports and airlines,” said a government official. “This will be a body blow to passengers as overnight, there will be a massive ticket price increase. Airports are natural monopolies and airlines will have no other option but to pass on the charges to passengers.”
The dispute began almost two decades ago, when the first round of airport privatisation took place in 2006.
Since data on assets and investment prior to the handover were unreliable, an agreement between the government and the two private operators made in 2006 provided for the Hypothetical Regulatory Asset Base (HRAB). This determined the asset value for the period from April 1, 2008, to March 31, 2009. HRAB reflects the notional value of assets used by the regulator to set tariffs, or charges, when the actual amount is not available.
However, DIAL and MIAL moved TDSAT, saying AERA must consider the value of non-aeronautical assets too. These assets include the likes of duty free shops, car parking and lounges, among others.
AERA’s methodology — that HRAB applied only to aeronautical assets — was upheld by the tribunal in 2018 and the Supreme Court in 2022. The two airport operators then filed an application in the Supreme Court citing a 2011 letter by the ministry of civil aviation, seeking to reopen the case.
The court passed the matter back to the tribunal, which, in July, overturned its previous order and supported the airport operators, saying non-aeronautical assets should have been considered by AERA.
The tribunal said in its defence that during the period under dispute, airport tariffs were being calculated based on the value of non-aeronautical assets as well.
According to TDSAT’s revised order on calculation of charges, the two airports should have earned Rs 50,000 crore more in tariffs, which is to be made up through an increase in UDF.
While this matter is sub judice, the issue of high airport charges has been repeatedly raised by lawmakers. Earlier this year, a parliamentary affairs committee summoned the ministry, saying charges have gone up multiple times after airports were handed over to private operators.
