I don’t know other elite program rules because I’m only Mosaic I didn’t expect people to be moved around for us and don’t even need to be in even more space seats. Our flight has rows of 3 together in exit rows. One of us is under 15 so I don’t think they’ll will allow us to sit there. I wondered if maybe they would bump a person to a different seat, possibly closer to the front, so we could sit together, Doesn’t matter now, I assigned our seats
