easy to make profits
"Easy" is not the right word, but "possible" would do......
From Ryanairs published Annual Report for 2011. Will 2012 prove much different, or worse? I rather doubt it, recession favours Ryanair, as does Olympic Games etc. I don't know what the RoC is, but further study of the numbers would provide that. Assuming that their declared 70m passengers are 1-way, that gives Ryanair a healthy (with high load factors) 53 Euros gross yield per 1-way passenger. How much of that is basic fare, and how much add-ons and other sales eg catering, is anybody's guess.
