Over 1400 Airbus A319 are due to be replacedHoly cow Batman I should load up.. And why would you do that Robin.. Because once the deal is closed then Airbus will retrofit some of its factories to build CS300's and Airbus will use ita formidable.marketing skills to sell the CS300 instead of the A319 CS 300 is more.fuel.efficient. lighter and can carry more passengers. Great idea Robin Lock me in for a truckload
