Amadeus has signed deals with 37 of the world's leading hotel chains to provide it with their best available rates.
Under the deal, the hotels will provide the IT and GDS company with rates that are the same or lower than those available through other distribution systems, branded websites or the hotels' own call centres.
Among the groups which have agreed the deal are Accor, Golden Tulip, Hilton International, Hyatt, Kempinski, Mandarin, Maritim, Scandic and Steigenberger.
Amadeus currently distributes rates for 58,000 hotels to 75,000 agencies, both on and off line.
The company said its hotel bookings had doubled in the four year up to 2005.
Antoine Medawar, managing director of Amadeus Hospitality Business Group, said: "Hotels are regaining control over their rates after the dark days of 2002 when they were forced to get rid of distressed inventory at rock-bottom prices.
"Since then, demand has returned and increasingly advanced revenue management technology has given hotels the leverage to direct their bookings through the higher-yield travel agency channel."
