The program is scheduled to run over six events starting next week (Friday, August 13) until late-October and will be available for properties on a global basis.
The online travel agency is not commenting officially on the launch of Flash Deals, so it is unclear if the program will continue beyond the initial run or widen in scope to include rental properties and other products.
The idea is to bring more business to partner hotels and attract new customers to Booking.com.
The discounts will take place every two weeks and on fixed days, lasting for just 36 hours. Over that time period, customers will get up to 30% off a selected room and rate.
Guests will have up to until August 2022 to use their discounted stay, according to documents issued to hotels seen by PhocusWire.
Hotels are being urged to promote the Flash Deals through their own channels, using creative assets provided by Booking.com, which send customers to the landing page of Booking.com.
The discounts must be applied to the original price of a room, before taxes and charge, as well as not being used in conjunction with other discounts the property might be engaged in, according to the documents.
