A passenger took the seat I had reserved for my daughter. I stayed calm and asked for help. Then the pilot handled the situation.

Lisa came through with the drink cart, and I watched her eyes linger on Ms. Reyes for just a beat longer than they should have. She didn’t offer her a smile. She didn’t offer her anything. She just kept rolling.

I watched as the flight attendant reached row 19. She paused beside the couple she’d spoken with during boarding.
