My husband, son and I would like to dive in the Caymans later this month. I'm new at all of this award booking and hopeful someone can point me in the right direction. Dates aren't that flexible - July 21 - 25, or 20 - 24 but that's about it. *A is where all of my points are. I've found some flights, going has low point options, coming home is the problem. I'm looking on the Continental site - should I actually call Continental for better availability? Call United or US Airways - will I hear something different from what I see ? I feel like it's a waste to use 47,500 miles for a coach roundtrip but if we really want an award ticket that may be the only options. Comments?
