I came across this article today and thought I would share it. As an author who understands the marketability of "free" I have seen my titles go out on Amazon for free and I have offered free giveaways. Here is another way books are going out for free and I think it is a great idea.
This a page from TeleRead a website dedicated to news about eBooks. The article goes on to say that a train company in Italy is offering passengers free ebooks to read while they travel. I would love to see this transfer to airlines as well.
