Jet2holidays is a British holiday company whose television adverts use a catchy, feel-good jingle to promote package holidays, and the advert's cheerful tone made it easy to reuse online. On TikTok, creators began pairing the sound with clips where holidays go badly wrong, from missed flights and lost luggage to storms on arrival, turning the original promise into an ironic punchline. The trend spread through short travel and comedy videos in 2025, and it remains popular because the contrast between the sunny advert and real travel chaos is instantly understood, even without any explanation.
