I have subscribed to the PFG for about 20 years and found Frequent Flyer Mag to be a useful utility with its listings of new services in all parts of the country. The online version is clumsy and not very useful and the book itself has to a large extent become superfluous with the profusion of online schedule utilities. I will have it for another year and a half because I too took advantage of the two for one offer early this year, but I think that is the end for me. Sorry, but I have no record of the code or the details of the offer.
