Just for the fun of it, I did a search for fares and came up with a fare of $762 on United. I have never flown United and am really unfamiliar with the program. The fare is V class. Is this upgradeable with miles? How many miles/points would it take? I have SPG, Hilton, and AMEX points. What are my options other than 24 hours in coach? I have CO Plat but nothing on United.
