As do many of the FT faithful on this board, I have a spouse who frequently accompanies me on our vacations with free trips. However, she flies very little herself, and rarely on anything other than a free ticket. As a result she has a few miles on a number of carriers, but no real likelihood of working up to enough miles to earn a free ticket anytime soon.
Just realized that the best use of her miles is to open a Hilton Mutual Fund account, with both of our names on it, and then take all of her miles and add them into our combined Hilton account. I figure that she has about 5000 miles on 4 carriers, one of which is American, so that converts to about 35,000 Hilton points. Enough for some good Hilton awards (especially since I can combine it with me @100,000 points).
I am sure someone here has figured out this strategy before and posted it, but i don't recall it, so I thought I would post it here again. Posted here instead of in Hilton, because it would be of interest to people who don't necessarily already have a Hilton account. My wife doesn't have one, but this is the best way to combine the small amounts of miles she has on several carriers.
