The new offering will be rolled out this year. However, only customers who have booked directly with Jet2, or its Jet2Villas or Jet2CityBreaks brands, will initially be able to access the range.
Jet2 told TTG that all attractions with cetaceans have been removed as part of the agreement with Musement.
Jet2 said agents will have access to "a diverse portfolio of thousands of experiences to offer customers, ranging from water park visits and boat trips, to sightseeing tours and off-road 4x4 adventures" at "a later date".
The Musement platform will enable independent agents to search and book experiences. The curated range of excursions, activities and attraction tickets has been designed with customer experience as the priority for Jet2 and Musement.
Steve Heapy, Jet2.com and Jet2holidays chief executive, said: “We are always looking at how we can further improve our incredible customer experience, and today’s announcement means our customers can choose from an even bigger selection of attractions and activities when enjoying their award-winning flights and holidays with us.
"Once live for our independent travel agency partners, this partnership with Musement will mean that they can offer a best-in-class choice of things to do, enhancing the Jet2holidays experience even further.”
Peter Ulwahn, Tui Musement chief executive, added: “This is a very important strategic agreement for Jet2 and Musement, as well as being a significant partnership to drive growth of the tours and activities market.
"Furthermore, this partnership reaffirms Musement’s position as the leading B2B partner for Tours & Activities, and our team is ready to work with Jet2 in providing great experiences for their customers.”
It comes just over three years after easyJet holidays announced it would sell excursions, attractions and activities from Tui Musement, while Fred Olsen Cruise Lines signed a deal with the provider in 2024.
