Though India became popular as a destination for holidays, Indians started to travel outside the country more often; the primary source and destination countries continued to remain the same. This is attributed to the fact that these countries are mainly where many Indians’ relatives live, or are relatively more affordable for consumers to travel comfortably. All the leading companies, whether in air transportation, lodging or travel retail, introduced their own mobile applications for both Android and iOS, the two most popular operating systems in the country. The apps became very popular as they allowed consumers to make bookings on the go, even when internet connectivity was weak. Leading Travel agencies have become quite popular among the young urban consumer base who are more willing to try new concepts and are looking for cheaper accommodation options, so that they are able to travel on a budget. Smartphone penetration has registered strong growth since 2009 in India. This is expected to continue over the forecast period. The penetration of internet-enabled smartphones is higher than any other mobile device in India. This combined with the convenience that mobile travel booking offers and the number of discounts available, will drive the growth of travel sales over the forecast period 2015-2019. India’s civil aviation industry is on a high-growth trajectory. India aims to become the third-largest aviation market by 2020 and the largest by 2030. The Civil Aviation industry has ushered in a new era of expansion, driven by factors such as low-cost carriers (LCCs), modern airports, Foreign Direct Investment (FDI) in domestic airlines, advanced information technology (IT) interventions and growing emphasis on regional connectivity. India is the ninth-largest civil aviation market in the world. “The world is focused on Indian aviation – from manufacturers, tourism boards, airlines and global businesses to individual travelers, shippers and businessmen. The first commercial flight in India took-off in , 1911, when a French pilot Monseigneur Piguet flew airmails from Allahabad to Naini, covering a distance of about 10 km in as many minutes. Tata Services became Tata Airlines and then Air-India and spread its wings as Air-India International. The domestic aviation scene, however, was chaotic. When the American Tenth Air Force in India disposed of its planes at throwaway prices, 11 domestic airlines sprang up, scrambling for traffic that could sustain only two or three. In 1953, the government nationalized the airlines, merged them, and created Indian Airlines. For the next 25 years JRD Tata remained the chairman of Air-India and a director on the board of Indian Airlines. After JRD left, voracious unions mushroomed, spawned on the pork barrel jobs created by politicians. In 1999, A-I had 700 employees per plane; today it has 474 whereas other airlines have 350. The aviation sector is one of the major economic drivers for prosperity, development and employment in any country, we know it. The rapidly expanding aviation sector in India handles near about 2.5 billion passengers across the world in a year and moves 44 million tons (MT) of cargo through 920 airlines, using 4,200 airports and deploying 27,000 aircraft’s in the world. Today, 87 foreign airlines fly to India and from India five Indian carriers fly to foreign countries and from 40 countries. Conclusion is The online medium – the Internet, represented by online travel agencies and Websites in the airline business, is today a powerful revenue generator for airlines. As indicated by market research data, almost 75 percent of air tickets today are bought online. e-Commerce and automation of business processes such as web check-in have largely enhanced the convenience of air travel. Added to that is the increasing popularity of the smart phone, which is expected to play an active role in customer relationship management and revenue generation in the time to come.
