( CNN ) -- Hollywood 's stars may have moved on from the red carpets of Cannes , but the real `` jet set '' -- the CEOs and executives who decide how , when and what we fly -- are heading back to France . The A-listers of global aviation will be at Le Bourget from June 17 to 23 for the 50th Paris Airshow -- the biggest and most important event in the industry 's calendar , where billion-dollar deals are done at the edge of the runway as stunt pilots swoop through the skies overhead . More than 2,100 companies from 44 countries around the world will fly in to showcase their wares at Le Bourget ; from jumbo-sized jets and massive manufacturing tools to the tiniest springs , cogs and other components , as well as high-tech concepts which may not see the light of day for decades . In years gone by , the show , held at the airfield where Charles Lindbergh landed after his pioneering transatlantic flight in 1927 , has seen the debuts of some of aviation 's key developments -- from Concorde to the Boeing 747 and the Airbus A380 .

With just days to go before the visitors arrive , it is still unclear whether the industry 's two most eagerly-awaited new planes , Airbus ' A350 and Bombardier 's C-Series , will be at the show . Both companies have warned the planes will be too busy carrying out flight tests to attend -- but industry experts say there 's an outside chance they may still be spotted in the skies above Paris . `` We 're still waiting to find out whether the A350 will put in an appearance , '' said Murdo Morrison , editor of aerospace industry magazine Flight International . `` That certainly would be a highlight -- it 's one of the newest and most exciting aircraft , but it and Bombardier 's C-Series are at a critical point in their development . `` It becomes a bit of a fight between the marketing people , the publicists , who want the company to get all the best headlines , and the engineers who are working to critical deadlines to get the plane ready to fly as soon as possible , '' he explained .

'' With or without the C-Series and the A350 , there will be plenty to look at , with flying displays , aerial acrobatics and all manner of military and commercial hardware ranged around the airfield for visitors to get up close to . Boeing is flying in not one but two 787 Dreamliners , and Airbus says that visitors will still be able to explore a full-size model of the A350 's cockpit and cabin -- whether or not the real thing arrives . Show organizers say one of the highlights of the show for the general public ( 204,000 of whom visited in 2011 ) is likely to be the flying demonstrations by a Russian Sukhoi Su-35 fighter jet . And fittingly , given that 2013 's event will be the 50th Paris Airshow , there will be some looking back : homegrown French plane manufacturer Dassault will celebrate the 50th anniversary of its Mystere 20 business jet -- the first of which will be on display at Le Bourget .

But Morrison said the real purpose of the event , and the reason for its significance , is the dealmaking and discussions that go on behind closed doors . Throughout the show , the conference rooms and chalets lining the runway will play host to scores of high-powered briefings and meetings ( in 2011 there were 151,000 trade visitors and 290 official delegations from around the world ) at which aerospace movers and shakers will shape the future . `` The real reason the Paris Airshow exists is the industry side of things , the chance for face-to-face talks between suppliers and potential customers , the 'down-in-the-weeds ' business discussions , '' he said . `` For some manufacturers the show is all about the race for orders , how many deals they 've signed , and others make a point of avoiding that . But nobody really goes to Paris and decides there and then , ' I like that , let 's buy two , ' -- it 's the meetings that matter . `` It 's not about past glories , it 's all about looking to the future : where the industry is going , rather than where it 's been .
