Air passengers must brace to continue to pay high airfares for some more time, as the air travel ticket prices are unlikely to cool down till at least July 2019, says a report. While domestic carriers are grabbing plum Jet Airways slots, the void created by the grounding of Naresh Goyal-founded airline is yet to be filled up. Around 480 slots out of 766 slots vacated by Jet Airways have been redistributed to other airlines such as IndiGo, SpiceJet and Vistara, The Indian Express reported citing government sources. Persistent high airfares will also take a toll on the passenger traffic, with the growth in the number of domestic travellers expected to moderate to 8-12%, CARE Ratings said in the report.
