You are forgetting the obvious from a Ryanair internal POV. To generate the next senior management you need people to get experience. 4 subsidaries which are sizeable airlines in their own right provide 4 times the number of people who can be provided with experience in running the whole of Ryanair. Failing to do this leaves Ryanair seeking some external candidates when MOL has had enough. Some of your management will not cut the mustard but quite a few will and whether the gain the top job or other you will have trained a whole new group of senior management.
