Tui cancels holidays for UK customers until at least end of June
Tui has extended the suspension of holidays for UK customers until at least the end of June due to coronavirus travel restrictions.
The UK's biggest tour operator had previously cancelled all trips up to June 11.
It has also suspended its Marella Cruises sailings up to July 30.
Tui said in a statement that it has extended the suspension of holidays "due to the ongoing travel restrictions".
Rival tour operator Jet2holidays has also suspended its holidays up to June 30.
A 14-day quarantine for international arrivals is due to begin in the UK on June 8.
The Foreign and Commonwealth Office (FCO) has advised against all but essential international travel since March 17.
Major UK tour operators will not run trips until the FCO changes its position.
Health Secretary Matt Hancock appeared to be more optimistic than in the past when asked about the prospect of people being able to go on holiday this summer.
He told BBC Radio 4's Today programme: "I think the answer is let's see where we get to."
Mr Hancock had previously commented that "big, lavish international holidays" were "unlikely" to be possible this summer.
Rory Boland, editor of magazine Which? Travel, said: "Tui's decision to extend its holiday cancellations means anyone with a holiday booked for June is now legally entitled to a refund.
"Tui must now start following the law and allow customers to claim a cash refund for cancelled holidays, rather than issuing them with credit notes they don't want."
