Hey, so I did a quick search and didn't find a fitting thread to write in, so don't shoot me if I've posted in the wrong place... Around a month ago, I upgraded my little sister on her upcoming flight on UA219 ORD-HNL, using an RPU. Up until one of the last few days, there has been a equipment downgrade from an international config 3-class (F,C,Y) 772 with lieflat seats in business to an Hawaii-config 777. I had reserved seat 6A (first row), and she has now been moved to a middle seat in a full cabin and is not able to change seats. When downgrading the product, I'd expect them to at least honor the seating preferences according to the reserved seats, in this case window. I also used the RPU, because I wanted her to experience flying in Business class, and I feel like I'm not getting the product that I "paid" for. Do I have any chance on getting compensation for this downgrade? Thanks!
