'Nothing beats a Jet2 holiday.' Except maybe viral fame.

Zoë Lister, the actress who narrated the 'Nothing beats a Jet2 holiday' British ad turned viral TikTok sound, said she never expected the audio to resonate worldwide.

The sound of the summer is actually not a song — it’s an ad.

“Nothing beats a Jet2 holiday,” a catchphrase from the British airline’s 2024 ad, mixed with English singer Jess Glynne’s 2015 hit “Hold My Hand,” has been used by more than 1.2 million users on TikTok, where it’s become a viral hit in recent months. Searches for Jet2 holiday have also spiked in the last month, according to Google trends.

The original Jet2 ad, which first appeared on the company’s YouTube page last year, shows a family of four as they catch a Jet2 plane to their beachside summer vacation.

From catastrophic weather at picture-perfect resorts to passengers misbehaving on flights, the videos often document travel-related setbacks.

No one was more surprised by the popularity of the ad than British actor Zoë Lister, the voice behind the viral audio. She recorded the ad about 18 months ago.
