NEW DELHI (AFP) - Indias government has approved the multi-billion-dollar purchase of 46 new aircraft by three low-cost carriers SpiceJet, IndiGo and Jet Lite, as air travel revives. The acquisitions worth a total of 190 billion rupees (4.1 billion dollars) were cleared by a civil aviation ministry panel this week and the new planes will start arriving in November, the Business Standard reported Saturday. Under the approvals, US manufacturer Boeing will supply 32 planes and its European rival Airbus 14. The hefty plane order by the low-cost airlines reflects their growing importance in the Indian market. Combined, the low-cost carriers fly half of all passengers in India. Indias airlines are rapidly expanding their fleets as the countrys economy rebounds from the global financial crisis, boosting the number of air travellers. Indian airlines carried a record 44m passengers in 2009 and Boeing has said it expects that number to increase by eight to 10 percent this year. New Delhi-based SpiceJet received govt approval for 30 Boeing 737-800s with delivery set to start from 2014. IndiGo, the countrys largest low-cost carrier with a market share of 16.9 percent, won approval for 14 A-320s for 2011-12. The third airline JetLite, a wholly-owned subsidiary of Jet Airways, has been granted permission to buy two Boeing 737-800s in November. The latest approvals came after the government last month gave in-principle clearance to fast-expanding IndiGo to buy 150 new aircraft over the next two to three years as it looks to fly international routes. That comes on top of 100 Airbus A320 jets Indigo ordered in 2005 for which deliveries will run until 2015. The company has given no cost for its planned acquisition spree but media reports have estimated it at around 650 billion rupees. The low-cost boom has forced full-service carriers Kingfisher Airlines and Jet Airways to start budget subsidiaries. They have shifted 60 to 70 percent of their total seat inventory to their low-cost operations JetLite, Jet Konnect and Kingfisher Red. Government-owned Air India is also looking at launching low-cost operations in the domestic sector. These capacity additions are set to take the number of low-cost seats on the domestic network to 80 percent, according to industry estimates.
