Thank you for pointing out that United Vacations may recant the confirmation to approve the stacked miles. It's certainly worth investigating and asking more questions. I found the deal over the weekend and by Monday the points were not stacking anymore. I had a screen shot from a mock reservation I'd made showing the points all stacked up. When I couldn't get them to stack up Monday, I had an agent re make the reservation then she sent it to the mileage rewards department, along with my screen shot. She requested they all be added onto the reservation the same way I'd had them over the weekend. I'm a travel agent actually, I rather like booking guests with United Vacations when they have the better deal. The customer service has always been great. I sure hope it's legit and they won't burn me!
