Hi Everyone..... I need some advice please. I just purchased travel from Orlando to Hong Kong for October 2015. We are going via San Francisco. The tickets were $900 r/t for economy. I am taking my wife who just overcame a pulmonary embolism a few years ago, and my father in law, that was one of two final places on his bucket list at 76 years old. I am trying to see if it's worth it to purchase miles from people willing to sell; we need 30,000 per person to upgrade to business class, so a total of 90,000 miles, plus I would pay an additional $600 per person to get business class. It's worth it for the room and given their past and future circumstances. I need some insight to see if people will sell their miles and I purchase, or should I forget it. Even when I look at economy plus, the agent indicated for me to purchase the global, and 10 people can fly for $2400.....that's steep for me for just this trip. I won't use UA after this, not from what I can see. Any suggestions on how this can be accomplished from those jet setters out here? o) Thanks!!!!
