Low-cost carrier SpiceJet is buying 155 planes from Boeing in a deal potentially worth $22 billion or 150 crores, including about 40 that were ordered earlier. The deal is a big and expensive indicator of how far SpiceJet has travelled from December 2014, when it was staring at collapse. "There was a time when most of you would ask when is SpiceJet closing down! Now for seven consecutive quarters, we are making profits. We are the number one airline in terms of on-time performance (OTP) and it has been an incredible journey for us," says Ajay Singh, the man who turned around SpiceJet after taking over from media baron Kalanidhi Maran in January 2015.
