Picking between Star Alliance and One World. I am very green to the frequent flyer programs, but was wondering which would be the path of less resistance to achieve free flights and more advantageous perks. I have read that in picking a program I need to know my goal, but in reality my only goal is to see the world. I will start at any continent or any country, as you can see my goal is broad which makes this choice tough. Thanks for your expert advice!
