If we take the fleet cost as cumulative cost of (a) flight operations, (b) flight equipment maintenance and overhaul and (c) depreciation and amortization cost, then IndiGo did not really gain much advantage over competition on this account. Its operational cost related to purely fleet and flying expenses were nearly the same as other LCCs such as SpiceJet and GoAir, while Jet Airways had a much lower cost. One possible reason for Jet’s significantly lower cost could be that it had already paid off much for the fleet being in the market for much longer.
