BRUSSELS, March 29 (Reuters) - Ryanair CEO Michael O'Leary said on Wednesday air fares could go up by between 10 and 15% this year, although he added they are unlikely to rise more than 20% as other airlines have predicted.
He said traffic was set to grow 10% this year for the low-cost carrier and the tempo of strong bookings could continue through the summer, driven in part by throngs of American tourists coming to Europe. (Reporting by Joanna Plucinska and Tim Hepher; Editing by Jan Harvey)
