Jet2 is a British holiday company whose television adverts, built around a catchy, feel-good song, became a huge TikTok meme as users paired the audio with holiday clips, travel fails and over-the-top vacation reveals. Chinese-language versions and remixes then circulated as short soundboard clips, offering the same instantly recognisable holiday hook in a different language for creators who wanted a fresh twist on a familiar trend. That language swap is part of the appeal, turning a well-known advert into a shareable joke that still reads instantly as a holiday moment.
