Budget carrier SpiceJet, the biggest winner of Narendra Modi government\u2019s affordable air travel scheme UDAN, is looking to expand further under the programme, planning to launch more discounted flights to the state of Kerala, CEO Ajay Singh said on Thursday at an event. SpiceJet also gave a glimpse of further expansion opportunities, with Ajay Singh saying that the religious destinations such as Kishangarh are \u2018incredible\u2019. Calling UDAN the most successful scheme of Modi govt, Ajay Singh said that UDAN has not only been noble but a commercially viable initiative. \u201cThe impact [of the scheme] has been tremendous\u201d, Ajay Singh said. He pointed out the government\u2019s ambitious plan to double the number of operational airports to 150 from 75 before the launch of UDAN. \u201cStates need to recognise that aviation is the fillip to economy and tourism of the state,\u201d he added. SpiceJet has grabbed most routes awarded under the scheme. UDAN, short for \u2018Ude Desh ka Aam Nagrik\u2019, is a scheme to boost regional air connectivity with private carriers operating short flights at government-subsidised airfares.

They should make markets viable and financially attractive to us. The states are competing with each other, there is no hiding of that,\u201d he said in response to a question. Using examples of UP and Karnataka states, which give concessions on flights with no direct connectivity to the destination, Ajay Singh said that the states must subsidise the travels and come up with a similar policy. Recently, Andaman and Nicobar have joined UP and Karnataka. Exemplifying Maldives\u2019 policy of involving hotels, Ajay Singh said that the state govt must include hotels to enhance the tourism industry. He said that the states tax themselves if they increase VAT as it keeps people away from them. SpiceJet has recently received rights to operate international flights under UDAN from Guwahati to Dhaka and Bangkok. Ajay Singh also said that their recently announced route which offers Delhi, Calcutta and Hyderabad connectivity to Orissa\u2019s Jharsuguda has great potential.
