TUI UK will kick of its Black Friday deals at one minute past midnight on Monday.
The promotion will run for seven days, until midnight on Monday November 26, which is two days longer than last year.
There will be deals available across TUI holidays, First Choice all-inclusive breaks and Marella Cruises.
It has launched a guide for customers telling them how to make the most of the promotion.
Details of the deals remain secret until the sale starts, but TUI has confirmed that, like last year, customers who book a Black Friday deal will automatically be entered into a free competition to win the cost of their trip back.
Entry is automatic for all customers who book a Black Friday deal online or in store.
