I have a free Gogo promotional code up to $17.95 value that expires 12/31/12. Dan, if you are flying soon and can use it, you get first dibs - the least I can do for all the $ you saved me. Otherwise, it is available for free for anyone flying before 12/31. I am new at this. I see that for private conversation there is PM that is used. What is that? How do I use it?
