Aviation Minister Ajit Singh has sent a stern warning to national carrier, Air India. He hit out at the cash strapped airline today, making it very clear that Air India has to get its act together because the government can;t keep pumping money into the airline. The struggling airline has reported losses of over 20,000 crores in the last 3 years. But Ajit Singh has ruled out any government help for another loss-making airline - Kingfisher Airlines.
