For the past several years, I've subscribed to the OAG skyguide. It's nice to have a listing of all the flights going back home as I head for the airport (to see if there's an earlier, or sometimes later flight). Call me a luddite, but I like to have a hardcopy of the flight schedules. I know there are some other sky guides out there. For my fellow luddites, which (hardcopy) guide do you like/subscribe to?
