Jet 2. 0 plans to resume operations in a hybrid mode (having features of both a budget and full-service carrier, or FSC) using brand new planes, say people in the know. The proving flight was conducted on a Boeing 737 that was used by Jet 1. 0, then taken over by SpiceJet and is now back with the former. Jet was launched in 1993 as an FSC and later acquired Air Sahara in 2007 — a financial burden from which it never recovered and eventually collapsed over three years ago.
