I read through the table of contents, and for your average person it probably has some good information that they don't know. If you are an FT regular then maybe you will learn a few things but you probably already know most of what is in the book. But still the average person is not going to spend a lot of time educating themselves on the inner workings of the airlines so it may represent some value.

I have not read the book, but I imagine it underscores the often overlooked point even on this board that with all the airlines the agents have extremely broad powers and discretions particularly at the airport, and really they can do what they want. If they want to for example they can upgrade you to first class on your dirt cheap coach fare. If they want too they can waive your change fee.

But knowing the above doesn't ensure you will get someone willing to do either thing, but I suppose if you know it can be done you are partially there.

I would bet you all three beers or more that the average person really has no idea about the discretion of a gate agent, etc. For example, the average American does not know a gate agent can provide a courtesy or operational first class upgrade which they can. The average person really has no idea how the system works and thus this book could help them.

Likewise there are things I don't understand about how different systems work, and an insider book for whatever that industry might be could help me.

Still even if "we" buy the book, I would not be surprised if you pick up a few tips and tricks you didn't know about. You never know it all, though you might know already most of what this person has to say.
