Hi, I'm new to the nonrev network, but coming up to speed pretty quickly. I would like to take my wife and 2 kids (one is 7, one is 1 and sits on a lap) to Moscow this summer, on the Atlanta non-stop (DL #46, Return DL #47). A friend is a Delta employee who has buddy passes. How many buddy passes would we need -- 3? 4? 6? 8? What's the chance of getting on the outbound flight in mid-July, and on the return flight in mid-August? Any thoughts and insights are greatly appreciated!
