Tui says it has "no plans" to reopen to customers on 15 June, despite getting the go-ahead from government at the weekend.
A spokesperson for the operator told TTG on Wednesday (27 May) the business was still reviewing how to reopen its retail network safely.
From Monday (1 June), Tui will increase the size of its retail team working to assist customers amid the coronavirus crisis to 1,100.
Most staff are working from home, but Tui said it was "looking at all options". It has not ruled out closed store working.
