Dear Joel,
First of all my compliments for an excellent book, just finished reading it and it’s great.
As a matter of fact there only seemed to be two copies left in the entire Greater London, at least according to the bookshop, and I bought one of them.
So far I have received two free upgrades within Europe and one Transatlantic upgrade to economy plus on United, all as a basic member. Hopefully I will be even more successful with my new silver-card.
Jacob
