The UK's biggest tour operator has announced plans to permanently close 166 high street stores as a direct result of the coronavirus pandemic.
Tui said outlets will close in the UK and Republic of Ireland as part of plans to expand digitally, though 330 high street stores will continue to trade.
It said the move will reduce its overheads by 30%, with approximately 900 roles affected.
The new model will result in a bigger "homeworking sales and service team".
"Customers value the personal service and support TUI travel advisors offer; the business is looking to move 70% of the 900 impacted roles into the new homeworking sales and service team," a statement said.
The decision was made following changes in customer behaviour, the company added.
"We want to be in the best position to provide excellent customer service, whether it's in a high street store, over the telephone or online, and will continue to put the customer at the heart of what we do," managing director Andrew Flintham said.
"It is therefore imperative that we make these difficult cost decisions, look after our colleagues during such unprecedented uncertainty and also offer a modern customer service.
"Customer behaviours have already changed in recent years, with 70% of all Tui UK bookings taking place online.
"We believe Covid-19 has only accelerated this change in purchasing habits, with people looking to buy online or wishing to speak with travel experts from the comfort of their own home.
"We have world-class travel advisers at Tui, so we hope many of them will become homeworkers and continue to offer the personalised service we know our customers value."
The news comes as the travel firm extended the suspension of holidays to the Balearic Islands and Canary Islands for UK customers until August 4 amid an upsurge in coronavirus cases in parts of Europe.

TUI said its holidays to mainland Spain remain suspended until August 10.
The Foreign and Commonwealth Office reimposed a warning against non-essential travel to the country on Monday.
This was a day after Spain was removed from the Department for Transport's exemption list for the 14-day quarantine requirement.
TUI is operating additional flights to Greece and Turkey this weekend to enable affected holidaymakers to switch their destinations.
The firm's managing director Andrew Flintham said more than 70% of customers with cancelled trips are rebooking to travel over the same period or in the coming weeks but to a different location.
He went on: "The summer holiday period is the most important time of year for travel operators and we are therefore doing everything we can to help customers get their well-deserved holiday.
"The health and safety of our customers and colleagues is always our highest priority.
"Importantly, we also call upon the UK Government to work closely with the travel industry and remove the blunt tool approach to quarantine and consider the rapid introduction of regional travel corridors.
"The level of uncertainty and confusion created this week is damaging for business and customer confidence in travel."
