This was what I was worried about. The flight is leaving from the US, so I was thinking the DOT rule applies. It also happened to me once on Southwest were the wife & 2 kids sat in one row, and I tried to sit 4 rows behind in the exit. The FA was immediately on it and told me I can’t sit there if we are all on the same reservation, regardless if the kids are not sitting with me.
