Tui said since restarting flights after the Covid peak, it had taken 1.4 million customers on holidays but had been hit by "continuous changes in travel advice by various governments" in its markets, leading to it cutting its capacity from 30% to 25% in the fourth quarter and moving to alternative low risk destinations.
Chief Executive of TUI Group, Friedrich Joussen, said: "Destination availability at present is highly influenced by government policy and development of the pandemic, meaning the environment remains volatile, and is likely to remain so for the next few quarters."
He added his voice to those of the airline industry in calling for testing to be made more available on arrivals and departures.
In a small glimmer of good news, Tui said it had secured a compensation deal with Boeing over the grounded 737 Max programme following the two fatal crashes at Lion Air and Ethiopian Airlines. Boeing is to pay Tui compensation for three years and defer 61 deliveries, allowing Tui to adjust its fleet capacity according to how the Covid crisis develops over time.
