A US travel blogger has sparked a debate over airplane seating etiquette after claiming that a fellow passenger cried for three hours when she refused to give up her aisle seat on a 10-hour flight. According to the blogger, the woman wanted to sit beside her husband, who was seated two rows ahead, but she declined to exchange seats. The incident, shared in a viral Instagram video, has prompted social media users to debate whether passengers should be expected to give up their preferred seats for couples who want to sit together.
