ive seen this quite a bit over the years when my wife and I were different status levels, and now both of us with same status but no status children. Despite the wording online which seems to suggest everyone on the same record should be right next to each other on the list (wording ‘same priority’), they aren’t always. My suspicion has always been the lower/no status person goes to the bottom of the list of the higher level. Ie, wife and I gold, kid no status all on the same PNR in T class, wife and I will be next to each other on the list, other golds in L and K (for example) will go be next, then our no status kid goes below the lowest fare class gold, then the silvers.
