Market leader IndiGo today followed its rivals and raised fares by 25 per cent to offset the impact of rupee fall and spike in international crude prices.         "IndiGo has revised upwards its fares, which are now 25 per cent higher than earlier," a source in the budget carrier said in Mumbai.        

When contacted, the Gurgaon-based airline declined to comment on the issue. The fare hike was triggered by Chennai-headquartered low-cost carrier SpiceJet, which increased fares by a hefty 30 per cent earlier this week citing rise in input costs in the wake of the rupee fall and a 6.9 per cent increase in the jet fuel prices by oil marketing firms from September 1.        

Full service carriers Jet Airways and state-run Air India, too, have increased fares by 25 per cent.
