Kingfisher Airlines is planning to convert some of its aircraft being used in the short-haul domestic sectors into all-economy configuration. Of the 66 aircraft in the airline’s fleet, 30 are short-haul — three Airbus 319, 19 Airbus 320 and eight Airbus 321.

“We are planning to change some of our aircraft being used in some of the short-haul domestic routes, with less demand for business class, to single configuration. The decision was taken after it was found that the single configuration Kingfisher Red fleet was giving more revenue,” said a Kingfisher executive requesting anonymity.

As per a report by Mihir Mishra in Business Standard, the executive said the airline was in deep financial crisis, but had not decided on any fixed number of aircraft to be changed. “Our business class seats are more spacious than other airline in the country. Due to which we have less number of seats and that impacts the revenue, as not all the routes have demand for business class seats,” he said.

The airline spokesperson did not respond to email and text messages. Kingfisher Airlines is the only listed carrier to have not turned profitable. It ended the 2010-11 financial year with a loss of Rs 1,027 crore. Hindustan Petroleum Corporation Ltd, recently stopped fuel supply to the airline for a few hours after the dues had touched Rs 650 crore, of which Rs 170 crore was not covered by guarantees.

The airline was also recently threatened by GMR, which operates Delhi and Hyderabad airports, that it will be put on a cash and carry system after the airline’s dues touched Rs 90 crore (Rs 68 crore for Delhi and Rs 22 crore for Hyderabad).
