Canada's Bombardier, Brazil's Embraer, European joint venture ATR, Russia's Sukhoi and Japan's Mitsubishi Aircraft do not roll off the tongue as easily as Airbus or Boeing, but in the lucrative Asia market there is room for everyone.
Embraer, the world's largest maker of regional aircraft, forecast in Singapore this week that the region will take delivery of 1,500 new jets of 70-130 seats over the next 20 years. That translates, it says, to a staggering $70 billion worth of business.
Importantly, for the likes of Embraer, the world's two largest aircraft manufacturers do not make aircraft that compete in the below-130 seat segment.
Low-cost airlines like AirAsia, Lion Air, and Cebu Pacific, with orders for hundreds of Airbus A320s and Boeing 737s, have driven much of the growth in the Asia Pacific airline market.
Increasingly, however, the major hub airports are getting crowded and there is growing demand for services to and between smaller second and third tier cities.
"The great opportunity in Southeast Asia is to get more people to fly, and that is about tier two and tier three cities," said Torbjorn Karlsson, who leads aircraft sales for Bombardier in Southeast Asia.
He identified countries such as India, where only about 1 percent of country's one-billion-plus population flies, and Indonesia and Thailand as inviting markets.
COSTA SEES ENORMOUS POTENTIAL
While there may still not be enough passengers to use the A320 or a 737, there is enough for smaller aircraft. And that is where the likes of Embraer and Bombardier come in. Thousands of this type of aircraft have been sold across Europe and the Americas, but relatively few have found their way to Asia. That's now changing.
Embraer announced its first major Indian deal in Singapore, with start-up Air Costa ordering 50 jets valued at $2.94 billion on Thursday.
In a country like India, where Airbus and Boeing aircraft have saturated the market with airlines like IndiGo, SpiceJet and GoAir, Costa is trying to find a niche for itself by connecting the smaller cities with Embraer jets.
""You don't need larger aircraft. This is enough for us," said Ramesh Lingamaneni, chairman of Air Costa, which began operations in October and now has four Embraer jets. "Regional air services have enormous potential in India."
Bombardier did not get any orders for its CSeries or CRJ jet aircraft, but Thai low-cost carrier Nok Air said that it would order up to eight of the Canadian company's Q400 turboprop aircraft.
ATR, which dominates the turboprop market, inked a deal to sell up to eight of its 72-600 aircraft to Thai carrier Bangkok Airways. It also agreed to sell 20 aircraft to leasing firm Dubai Aerospace Enterprise, with options for 20 more, in a deal valued at $1 billion.
Sukhoi displayed a Superjet in the livery of its customer, Indonesia's Sky Aviation, on the static display at the show. Japan's Mitsubishi Aircraft and China's AVIC are also developing aircraft that are expected to compete in the segment, and their executives were busy trying to impress potential customers in Singapore.
"There is lots of room to penetrate more into this market," Paulo Cesar Silva, president and CEO of Embraer Commercial Aviation, told Reuters.
"You have to have the right aircraft. In the U.S., until two years ago, Delta was flying four times a day on the Boston-La Guardia route using A320s. Now, they place the E-175 11 times a day. You keep the frequency, the load factor is high, and the passenger is happy as every time you head to the airport, there is an aircraft leaving."
There is intense rivalry within the segment too, with turboprop operators like ATR pointing out that their aircraft are more efficient over these short-haul routes.
"I think it's partly the economics. On this short distance route the turboprop is the most efficient aircraft. Jets burn twice as much fuel, so costs are much higher. And a lot of these airports are not accessible for jets," ATR's head of Global Sales, John Moore, told Reuters.
