He also argued, "It's why Ryanair has a lower competitive cost of any other airline in Europe most of whom fly Airbus." He said the average flight time on his European routes is about 90 minutes to two hours at the cost about $40 a ticket — half the average cost of one on Southwest Airlines.

O'Leary certainly doesn't shy away from controversy, once saying he wanted to take the back bathrooms out his planes. He told CNBC that regulators won't let him, but if he was able to swap in the six extra seats he wanted, ticket costs for all his passengers would be "lower by another 5 percent."

Commenting on his inquiries into creating a "standing-room only" section in the cabin like on trains and buses, O'Leary said the vision there could be that one day, there'd be so much room that passengers could fly for free with the airline making money "selling snacks and the other stuff."

As for the bailout that would require taxing Cyprus bank savers, O'Leary said, "[We] are the largest airline in Cyprus … but we don't have any bank accounts or deposits in Cyprus, thankfully." He said Ryanair shut them down about a year ago "because there was always a danger of some kind of run on the Cyprus banks."

O'Leary added, "What the Europeans are doing is insane … you can't go in there and steal people's money out of the banks." He said it could "undermine the whole European banking system, if people can't rely at least that their money is safe in banks."

In a couple other southern European trouble-spots, Italy and Spain, O'Leary said Ryanair is the No. 1 airline in those countries and it has bank accounts in each. He said he's had conversations about pulling money from Italy and Spain but he expects things there will calm down.
