Michael O’Leary, CEO of Dublin-based budget airline Ryanair (RYAAY.NASDAQ, RYA.LSE, RYA.ISE), said that the emergence of Commercial Aircraft Corporation of China (Comac) is a “game changer” in the air supply industry, The Wall Street Journal reported. O’Leary was in China to tour Comac facilities this week. “You could not fail to be impressed by the resources they are putting into” the program, he said. The C919, Comac’s featured plan, is expected to begin testing in 2014 and ready for delivery in 2016. It would compete with the Boeing 737 and Airbus A320, costing around US$32 million. For its part, Ryanair expects to order more planes possibly as early as 2014. O’Leary has been in discussions with Comac since early this year on a bespoke C919 that could save 10% on similar Boeing and Airbus models.
