It's now official that low-cost airline IndiGo is indeed the biggest beneficiary of Vijay Mallya-owned Kingfisher Airlines' slow death, as the young carrier has become the new market leader overtaking Jet Airways, but there are several reasons behind this feat. IndiGo took over Jet Airways in terms of market share four months ago, but in July it took over the Jet Airways Group, which includes its low-cost arm JetLite, flying 27% of the total Indian passengers as opposed to 26.6% flown by Jet.
