It's something travel experts call "set jetting" - a trend that has frequently boosted tourist numbers at filming locations.

Data given exclusively to the Sky News Money blog by Expedia shows popular BBC reality series The Traitors - filmed at Ardross Castle - has caused searches for hotels in the Highlands to rocket.

A month after the final episode of the first series aired in 2022, there was a 72% increase in searches.

During the same period, flight searches in the Scottish Highlands also increased by 32%.

Meanwhile, the Jamie Dornan-led series The Tourist appeared to boost searches for holidays in Adelaide in South Australia.

Two months after the first season aired, there was a 56% increase in hotel searches for Adelaide.

Flight searches increased by 37% in one month.

With both series currently airing their second season, it seems likely they could each prompt another increase in travellers.

Expedia previously predicted 13 more TV and film locations likely to be popular in 2024, based on show and film releases and travel data.

• Thailand, inspired by The White Lotus season three
• Paris, inspired by Emily In Paris season four
