The Jet2holiday sound comes from Jet2holidays advertising and became widely reused online as a meme sound on short video platforms in the 2020s. Creators turned the upbeat travel tone into a reaction format by placing it over clips where things go wrong, especially holiday, airport and pool footage. Its popularity comes from that instant contrast between polished advert optimism and visible chaos. It is still used because the opening is immediately recognizable and easy to sync with abrupt visual punchlines, much like a vine boom sound in travel meme form.
