I've got a long range plan. In 3-5 years, I want to take the family (myself, my bride and my 3 little ones PLUS her parents and my mom and her boyfrield) on a two-week trip through Europe.
I haven't really figured out how many miles I need yet (especially since the reward levels could easily be different then), instead focusing on simply earning them. I hope to get around 150K by the end of this year, and earn 200K a year thereafter.
