Commuter book gets you 10 one-way tickets at a total of $1499. Good for a year. You could see if there is someone else that needs some and work something out. We buy a book and manage to use it in a year as we make more than one trip and often have others with us. Got our last book in July on a trip with just the two of us, then flew down with 3 of us in Nov so we used up the rest.
