Tom,
do you honestly think that Ryanair makes its profits out of their mostly really low fares? I dont. They make their money also out of tax cuts, EU subsidies, local subsides and on cut to nonexistant airportfees etcetc.
Look at Hahn, where they dont pay for anything at all. Running an Airport does cost a penny. The burden is on the taxpayer and the other airlines and users who pay for the missed income from Ryanair.
So the cheap fares are not so cheap in the end. One can debate if the "old system" was good, but at least it was more or less honest.
The day Ryanair does not receive any taxmoney, pays for the airports on an even level and still writes at least a black ink zero, IŽll withdraw all critism.
