Query: excellent, informative, explains competition well

After reading about 1/3rd of the book: well-written overview of competition in the airline industry with a lot of good detail, for example on airline customer loyalty strategies like frequent flyer programs, agency discounts, corporate discounts. Explains the economic theory in context. My only complaint is that a lot of charts with mind-numbing numbers in them would be more usefully presented as graphs rather than numeric tables.
