Indian airliners IndiGo and Air India Express have been ranked among the top five cheapest airlines in the world.
The two airlines also provide international connectivity.
While the Air India Express, the wholly-owned subsidiary of state-run carrier Air India has been ranked second, the budget carrier IndiGo is placed at fifth position in a Global Flight Pricing Report.
The report has been prepared by the Melbourne-based Rome2rio — a multimodal travel planning site.
The other Indian carriers that figure in the list includes Jet Airways at 12 place and Air India at 13th position.
Air India Express, mostly connecting Gulf countries and Singapore, has an average cost of $0.08 per km and IndiGo $0.10 per km.
The latter connects Indian cities with Gulf countries besides Bangkok, Colombo and Kathmandu.
None of the airlines from the UK or US found a place among the top 10 affordable airlines in the report.>
