Read the post from LGS6753, don't know the RAC man personally but the post is absolutely correct, you don't need to be a 'Name' to run a business successfully.
Now the contentious bit..... I DO know Michael O'Leary personally, I mean know him not just heard of him or seen him, let there be no doubt he is one of the greatest entrepreneurs in the airline business today, not one of the most popular but when it comes to pleasing the shareholders that doesn't matter.
Good luck easyjet and your new leader!
