I would second stut's point. I certainly do not live like a monk, but my usual travel within Europe is on the basic fares as advertised, without paying a penny more on top. Of course I travel hand baggage only, but I prefer to do that anyway. There are also no fees for paying by credit or debit card now as these aren't allowed.
The point is, if you travel light and aren't bothered about extras, then the price you see is the price you pay.
