It still amazes me when people make comments of saying Ryanair might not be here in a few years time.
Ryanair is not just an airline - yes this is a core part of the business, but it is a brand. Income comes in from advertising to hotels, credit cards to travel insurance to home insurance to anything-else-you-want (well not quite, but you get what I mean). How are these products sold - through Ryanair.com. How do you get people to the site - LOW FARES and high publicity.
What Ryanair loses in revenue from seats it will be making up elsewhere through deals and other ventures realted to the Ryanair brand.
Narrow-sighted professionals still see this as an industry back when airlines could charge high fares attract passengers and get away with it - now im afraid, the travelling public are not so stupid, so airlines like Ryanair and easyJet will survive as they continue to diversify and offer cheap, affordable travel with consistent performance.
