Air India has been put on cash-and-carry mode by Mumbai Airport authorities as it has failed to clear the dues in the required time which mounted to Rs 450 crore . The airline, however, today said it has paid about 40 crore rupees and certain outstandings were yet to be reconciled. The Mumbai International Airport Limited, which runs the city airport, yesterday communicated its decision to the Air India management. Sources said, the national carrier has been told to pay at least Rs 200 crore by June if it wanted to be taken off from the cash-and-carry mode. Senior Air India officials told media that Air India's flight operations out of Mumbai would not be affected. The dues relate to various airport charges like those for landing, navigation, parking and other services, which an airline has to pay to the airport operator.
