MEDIA-Ryanair set to double German market share to 20 pct-CEO
* Ryanair will increase its market share in Germany to 20 percent in two to three years, CEO Michael O'Leary tells German weekly Frankfurter Allgemeine Sonntagszeitung
* O'Leary predicts Lufthansa (Xetra: LHAB.DE - news) will have bought Air Berlin within three years
* O'Leary says that the fact that Lufthansa is leasing planes and personnel from Air Berlin (LSE: 0GPE.L - news) is equivalent to a takeover but competition authorities don't want to admit that
* O'Leary expects Lufthansa will shut its budget airline Eurowings or merge it into the rest of the group within a few years as its costs are three times higher than at Ryanair
* Ryanair does not want to become a low-cost provider of long-haul flights as it has not been able to get slots for reasonable prices, O'Leary says, adding that new opportunities might arise due to the fact that Gulf airlines are having financial problems Further company coverage: (Reporting by Frankfurt Newsroom)
