Why does Maxwell say the airhostess was “the very queen of her kind”?

Luckily Maxwell got a seat in front. He covered the floor with newspaper. He rang for the air hostess and gave her a parcel of fish to keep in cool place. He took her into his confidence about the incident with the box. She suggested that he might prefer to have his pet on his knee. Hearing this, he developed a profound admiration for her, for she understood the pain of both the otter and its owner. This is because he calls the airhostess “the very queen of her kind”.
