Various cost cutting measures implemented by Air India have resulted in savings of approximate Rs 800 crore during 2010-11, civil aviation minister Ajit Singh said on Wednesday. He was replying to a question in the Lok Sabha and also listed the measures which resulted in reduction of expenses. Rationalisation of routes, phasing out of old fleet, closure of overseas offline offices, dismantling of the Frankfurt hub and establishment of Integrated Operations Control Centres were some of the measures that Singh said had reduced Air India losses.
