India is a massive country both in area and people. The combination should give it advantages to grow fast and generate economic progress. But it hasn’t yet and the new, much praised Prime Minister, has yet to unleash the pent up forces held back by a bureaucracy that is surely the envy of every Soviet apparatchik.
Take a look at the country’s airlines in the following chart. Some of the airlines, like Kingfisher, have gone. Overall, the Indian commercial passenger fleet grew from five airlines with 104 aircraft in 2000 to 16 airlines with nearly 400 aircraft. This is robust growth – but India’s railways still carry more people in one day than its airlines carry in a year. So it’s not robust enough.
Looking at the passenger fleet by aircraft type, as the next chart shows, provides an idea of how these airlines are developing markets. In 2000 the fleet was 67% single aisle and 33% twin aisle. By 2014 the fleet was 73% single aisle, 17% twin aisle along with 7% regional jets plus 3% turboprops. The much smaller fleet of twin aisles reflects a shrinking of overseas capabilities (Air India falling and external competitors having a field day). At the same time the growth in regional jets and turboprops (sparse data prior to 2009) makes sense given an opening of domestic air service, many of which depend on rudimentary runways and obviously sparse traffic.  Low GDP is a crucial hurdle to faster growth in air travel.
The next chart tracks turboprops in India from 2009. The failure of Kingfisher impacted the size of the fleet, but look at how few turboprops there are in a country of 1.2 billion people! One would think the market would be many times this.
