New Delhi, March 5 -- Air India has expressed concern that Delhi International Airport Ltd's (DIAL) proposal to significantly increase user development fees (UDF) and other aeronautical charges will hinder efforts to establish the airport as an aviation hub.

In a written response to the Airports Economic Regulatory Authority of India (AERA), the airline recommended reducing charges for wide-bodied aircraft to encourage the use of larger planes on domestic routes.

DIAL has proposed raising landing charges for domestic wide-bodied aircraft from Rs.188 per metric tonnes (MT) to Rs.325 per MT, and for international wide-bodied aircraft from Rs.250 per MT to Rs.430 per MT. MT refers to the plane's weight.
