Holiday company TUI said that it had reduced capacity for the coming winter season due to changing travel restrictions.
TUI also said it continued to evaluate options to boost its balance sheet which has been strained by the Covid-19 pandemic.
The Germany-based group is the world's largest travel company.
It said today its liquidity stood at €2 billion on September 20, down from €2.4 billion in mid August, with the reduction due to higher customer refund obligations.
Travel restrictions have hit the company hard, forcing it to cancel trips and change its schedule, and rising coronavirus infections across Europe mean it has now reduced its already shrunken winter season by another 20%, it said.
That means less future business, heaping more pressure on the group's finances.
"We continue to evaluate options to achieve the optimal balance sheet structure to support the business over the longer term," TUI said in its statement.
Sources say that TUI is considering a share sale of up to €1 billion to prop up its balance sheet. A German government bailout of €3 billion in debt has helped it survive the crisis so far.
TUI stuck to guidance that for its summer season next year it will operate 80% of its adjusted capacity and said it was encouraged by early bookings.
