My wife has her status matched to my 1K because I am a MM, but it feels like she is not treated the same way. In particular, the last three times she's flown solo she lost her previously reserved aisle E+ to a middle seat. In all cases she double checked the seat after booking and there were no equipment swaps. United has been unrepentant when the issue is raised as you'd expect. Is she just unlucky or getting treated worse because of her matched status? I fully realize this is a bit of conspiracy theory, so thanks for entertaining it.
