I had the idea, if organized, you can cross them around to work together. For instance, Alaska is a middleman doe so many.
I started without a goal( biggest error), I still had great times and smaller great travels ( all over Mexico, New Orleans jazz fest this week!!!) but now something huge comes up and I'm screwed but at least I'm not SOL, or am I.... Maybe I should just be saving for full price but that seems like such a failure or waste
