Thanks, we will be in the Schengen area in the Paris airport, so not sure what might happen there.

But my son has a different last name than me, since I divorced his dad and remarried. That plus the different skin color (he's Hispanic, I'm Anglo) is usually enough to raise eyebrows, even in this modern world. When he was a baby, I had flight attendants quiz me about whether I'm his mom, and passengers in the airport ask me repeatedly how he could possibly be my son with his curly hair and the straight hair of myself and my now ex (who is Hispanic, so they assumed that perhaps he was the dad and I was a stepmom.)
