I do see your point but the business is segmenting: segmentation by brand has been take to a new level by the locos and their revenue streams have moved from the traditional one ticket buys everything to pay as you go.
Conversely, while the airlines have been adopting, more and more, the pay as you go method, hotels /resorts have been turning more and more to the all inclusive concept.
Perhaps it is because a flight is becoming less of a discretionary purchase than a 2 week holiday and the consumer sees it as a necessary evil to get from A to B rather than as an integral part of their holiday.
Competition also lowers prices: if you compare like for like stage lengths where there is / are multiple carriers with monopolies you will find the a vast variation in pricing.
In due course Ryanair will evolve, as will BA, Virgin and every other carrier: the process is dynamic, driven by incremental small changes introduced somewhere and adopted by many.
Whether we are still working, or long retired by the time the change takes effect is a moot point.
