Flying out of the Chhatrapati Shivaji International Airport in Mumbai is set to get costlier with an additional levy of up to Rs 120, to fund the metro rail connectivity to the aerodrome, coming into effect from April 1.

Tariff regulator Airports Economic Regulatory Authority (AERA) had in January this year allowed Mumbai International Airport Limited (MIAL) to charge an additional levy of Rs 20 from each domestic flier and Rs 120 from each international traveller as development fee to fund a metro rail project.
