A Thai airline will allow passengers to purchase seats for life-like dolls that their owners treat as real children due to their belief that they possess supernatural powers.

Thai Smile Airways, which is a part of national carrier Thai Airways International, said in an internal memo that dolls with tickets will be served snacks and drinks, though they will be barred from sitting in exit rows. Owners who take dolls on the plane without tickets will have them treated as carry-on luggage.

The dolls known as Luk Thep, or Child Angels, have become increasingly popular in Thailand after several celebrities extolled their benefits. The dolls, which can sell for hundreds of dollars, are thought to possess the spirits of child angels and their owners pamper them with brand-name clothes and accessories due to the belief that a well-cared-for doll will bring good fortune.
