I’m planning a trip around the world for June/July 2011. My question is concerning airline miles: I know most major credit card companies, as well as major airlines, offer rewards programs that give you “miles”. I was just wondering what would people recommend would be the most useful for someone doing a lot of international traveling, and which airline card or bank card i should use? I’m trying to maximize my miles so hopefully by the time i start traveling i’ll have a bunch saved up. Any idea how many miles it costs for flights around Europe and Asia? I’m planning on doing most of my travel overland, however I plan to fly from Barcelona to Athens, From Athens to Tel Aviv, From Tel Aviv to India, and from india to China. Any help would be greatly appreciated.
