I'm flying to Australia in 3 weeks. I'd like to take advantage of getting the most miles for the trip. I have to fly United so I can travel with my wife. My plan is to open a United Airlines credit card and put the trip on there. Is this my best course of action, or is there a way to get more miles or a different way of doing it?
I was also wondering where I could go to pay someone to use their United Airlines miles so my wife and I could be upgraded on the trip there. Any information is greatly appreciated.
