Michael O'Leary predicted European airfares will rise 10-20% next year, the biggest increase in history over the next 12 months.
"You could see airfares rise next year in Europe. I think by 10, 15, maybe 20 percent," Michael O'Leary, CEO of the European low-cost carrier Ryanair, said this week in Belgium. "You're going to see the biggest increase in airfares, I would say, in history in Europe in the next 12 months."
