Jet2holidays is to stop selling tickets to attractions featuring orcas, whales and dolphins.
The policy shift covering cetaceans has been claimed as a victory of a two-year campaign by animal protection group Peta, which is continuing to lobby Tui on the issue.
EasyJet holidays announced earlier in March that it will not promote or sell tickets to any attraction or tourist activity where animals are exploited.
Expedia, Thomas Cook, British Airways Holidays, Virgin Atlantic Holidays and Club Med have previously ended the promotion of such attractions.
Peta vice-president of programmes Elisa Allen said: “Jet2holidays made the right call to cut ties with parks that confine orcas and other dolphins to concrete tanks that are to them the size of bathtubs and force them to perform circus-like stunts for human entertainment.
“All eyes are now on Tui, which must follow Jet2holidays’ lead.”
Jet2holidays said in a statement: “A key driver of our success is the fact that we continually review every element of our operation, and as part of that process we encourage and welcome feedback from a range of stakeholders.
“This has enabled us to build an award-winning business which, as well as leading the industry for customer service, is also the UK’s largest tour operator.
“Consequently, and following a thorough end-to-end review, we can confirm that Jet2holidays will no longer sell tickets to venues which feature cetaceans (orcas, whales and dolphins) for entertainment.
“This comes into effect from 27/03/2024, however we can confirm that all existing bookings will be honoured.”
