( CNN ) -- Plane makers swooped to conquer at Asia 's biggest air show but rather than picking up any huge deals , smaller agreements and partnerships were the order of the day . The event still saw $ 31 billion worth of deals announced ; triple the total of the previous show in 2010 . However , two thirds of that was down to Indonesian low-cost airline Lion Air formally sealing its deal for 230 next-generation Boeing 737s , first reported last year . `` The fate of the commercial aviation industry generally follows the fate of national economies , '' says Siva Govindasamy of Flightglobal . `` The mood generally is a little bit uncertain , but ( the outcome from the show ) is a little better than expected . '' Indonesia 's economy is one of Asia 's fastest growing -- GDP grew there by 6.5 % last years -- and Lion Air also announced another deal this week for a fleet of short-haul planes from ATR for its subsidiary , Wings Air . Budget Indian airline Go Air joined the billion-dollar deal club by signing an agreement with engine maker Pratt Whitney , worth around $ 1 billion . `` ( These deals ) shows a greater trend that developing countries are leading the world in demand ( for new planes ) , '' says Govindasamy . `` Indonesia is an underdeveloped market ; there is no doubt there 's great potential in the region . '' But on the same day that Air Australia went into administration stranding 4,000 passengers , there is some apprehension that the region could be blighted by airlines with too many planes and not enough passengers to fill them . `` When airlines start to fail that 's a bit of a worry . India definitely has over-capacity . Any airline has to be cautious about adding capacity irrationally . Historically the airline industry has n't done that , '' says Govindasamy . AirAsia has found itself in a good position , and perhaps an example to others , says Govindasamy , by building up a good base in its home market before taking on the world . `` If you do n't get the base right , you wo n't succeed in this industry . '' The week also saw Chinese plane maker Comac announcing another corporate client ( Bank of China ) for its yet to be built C919 jet . But these smaller deals belie the impact China 's aviation industry may have in two years ' time when the jet is first trialed , believes the Singapore Air Show organizer , Jimmy Lau . `` The market is very dispersed in China , but when the Comac C919 plane goes to market its capability will be stronger , '' he says . China 's market is unique and Govindasamy believes its airlines are in a good position to not do things irrationally . `` They are doing a lot of things right , but then they are supported by the government and often fulfilling a national need in terms of flying routes that might not be so profitable .
