I figured this was the case. Unfortunately, we have 1 or 2 nervous flyers who want to fly as part of the group, so this limits our options if partner inventory is limited. (As it is, they already are in Y on the partner flight, not that it matters much in Europe.) I'm in Europe and I just don't feel like dealing with this issue to sort it out with them right now, especially on Super Bowl Weekend.
