I bought this book, but can't say I'm overly impressed so far.
It seems to be mainly the author being really pleased with himself at the puns he has thought up (Ruinair, EZjet, L'eau cost airlines etc. etc.) and also some strange comments.

For example: "Stansted Airport is connexted to Liverpool Street Station". What does this mean? Connex never had the rail franchise for this route, but had a bad reputation and lost the franchises they did have. Does he mean that the service is as bad as Connex, and if so, why not name and shame the operator? Or is it just bad research, or a good play on words?

The book is full of this and it makes for a jarring read. Much better is the more matter of fact book "Ryanair: How a Small Irish Airline Conquered Europe" which actually has more horror stories but also more achievements.
