(kept the title of this thread somewhat generic to help with search and keep this thread generically useful) I am managing the OnePass account of a family member. I set it up for her when I paid for a flight for her, and it currently has about 3600 miles in it. She's never flown UA or CO again and it's quite unlikely she will in the forseeable future (and if she did, putting the OP number into the booking would likely be the last thing she'd think about doing... earning mileage rewards just not something she's spending time on). Anyway, with the pending merger, those 3600 miles will turn into MP miles and become subject to the new expiration policy. Time to start thinking about what to do with them... Looking at the OnePass and Mileage Plus site, it appears there isn't a whole lot these are useful for. - I could subscribe to a magazine for the next five years or so, but I already have piles of unread ones that p*$$ my wife off, so adding to them wouldn't be a wise choice. - I could transfer most of the miles into my own account for around $45 ($15/1000 miles). I'd rather keep my $45 - I could try and somehow acquire more miles into that account to get enough for an award (eg intra island HI for 5000, though no plans to fly intra-HI) or one-way domestic (12500). Are there any transfers into CO/UA's programs that are cost-effective and don't require the names to match? - I could donate them on the CO/UA website. Any other ideas?
