Looking to go to Cape Town with family to visit daughter-in-law's family. Thinking March 2014. I know it is way too early to book but when I look at September and October 2013, all that is available is one date in October. Is this a difficult flight to find seats on. Would love to go First but will settle for Business. Any advice you can give me? Have lots of UAL and about 80,000 UR points at this time but if I need another airline's miles then I can get them in the next few months before it is time to book.
