Question, i have a little bit of a funky idea, wondering if this would work. I have 2 vouchers of buy one and get the next two for $99 that expire end of 2015. I would really like to use these in January 2016. What i was thinking is to buy the tickets for 2015, then upgrade it to a higher class with Points and cash, and then call up to switch the dates on the tickets. Anyone ever hear of something like this? Think it would work?
