Tui’s Atol now stands at around 3.74 million passengers, down from the 5.55 million protected passengers it was licensed to carry during 2019/20.

Jet2holidays, meanwhile, has cut its allocation from last October’s 3.92 million to 3.48 million for 2020/21 as the Covid crisis bites.

Jet2’s Atol peaked at around 4.8 million passengers in May this year owing to extra capacity added over the winter and into the new year following the collapse of Thomas Cook, with summer 2020 forecast to be its biggest and busiest summer to date.

This, however, was scaled back as coronavirus made many of Jet2’s primary destinations unviable.

The new figures represent a much bigger reduction in allocation for Tui than Jet2 though, with Tui’s Atol down 1.81 million passengers (-32.5%). Jet2’s, by comparison, is down just 440,000 passengers (-11.2%).

On the Beach (1.22 million) and loveholidays (1.06 million) remain third and fourth in the list, with British Airways Holidays fifth with 599,000.

EasyJet Holidays is sixth with a licence for 547,000 protected passengers, while easyJet itself carries a licence for 342,000.

It is unclear though whether the size of easyJet Holidays’ Atol reflects the true scale of its ambitions after it was relaunched earlier this year, owing to the impacts of the coronavirus crisis.

In total, the UK’s top 10 Atol holders are now licensed to carry just over 12 million Atol protected passengers in the 2020/21 renewal window, which runs to the end of September 2021.
