Maxwell calls the air hostess "the very queen of her kind" because she was extremely friendly, kind, and helpful towards him and his pet otter, Mijbil. She showed great understanding and kindness by taking Maxwell into her confidence about the incident with the box and generously suggesting that he put the otter on his knees during the flight to make it more comfortable. This thoughtful and compassionate behavior made Maxwell deeply admire her, as she understood the pain and discomfort both the otter and its owner were experiencing.
