The immersive Discover More range uncovers Jet2City Breaks destinations with tours and experiences included in package options.
Kraków and Marrakech are joining the Discover More roster, with the former including a tour of Auschwitz and a tour of Marrakech's historic city included in the latter.
Discover More options in Marrakech are operating from winter 2024/25 with summer 2025 options also available from Birmingham, Glasgow, Manchester and London Stansted.
Kraków packages are available for summer 2024, winter 2024/25 and summer 2025 from Belfast International, Birmingham, East Midlands, Glasgow, Leeds Bradford, Liverpool John Lennon, Manchester and Newcastle International.
Packages include flights with Jet2.com, 22kg hold luggage, 10kg hand luggage, and accommodation.
Steve Heapy, CEO of Jet2.com and Jet2holidays, said the expansion is founded upon "demand from customers," and the operator is sure "these new packages to the city break destinations of Marrakech and Kraków will be very popular.
"From speaking to customers and independent travel agents we know that there is a growing appetite to learn more about these historically vital locations, and they add a lot to our growing Discover More collection."
Packages to Marrakech lead in from £379 per person based on a January 2025 departure, with Kraków packages from £599 per person based on June 2025 departures.
The Discover More range is available in a host of city break destinations including Porto, Iceland, Bergen and the Fjords, Turkey, Malta and Croatia.
