Lion Air , Indonesia ’s biggest airline , is reportedly forced to cancel its outstanding orders for Boeing 737 planes following what co - founder Ali Kirana called the US manufacturer 's " very inappropriate " response to a deadly Lion Air crash in October . They are thought to have been to blame for a system error which repeatedly forced the Super Max 737 's nose down , despite pilots ' efforts to regain control . Critics have said Kirana 's plans to cancel the plan orders are at odds with his ambition to expand the Lion Air fleet to 1,000 aircraft .
