On the face of it, IndiGo is sitting pretty. With a handy 40% market share and a route connectivity that its rivals would give their right engine or CEO for (in fact, GoAir just ended up doing the latter), coupled with an incredibly tight-cost structure, IndiGo is in cruise mode. The airline has been around for a little over a decade and managed to come up trumps where most players have succumbed to either strategic mistakes or financial woes.
