Amadeus, Travelport and Sabre have briefly tossed their differences aside to come together to back the launch of a fundraising programme to help support global health projects.
The trio have joined a number of other travel firms to back MassiveGood, a project which allows US travellers to donate $2 every time they book a air ticket, buy a hotel room or rent a car on the web.
MassiveGood is led by former US president Bill Clinton, United Nations' secretary-general Ban Ki-moon and a string of musicians, actors and other politicians, including UK prime minister Gordon Brown, to raise money for projects to fight HIV/AIDS, malaria and tuberculosis.
A film to support the launch, featuring Samuel L Jackson, Susan Sarandon and directed by Spike Lee, was unveiled today at the UN in New York.
Available in the US from today, MassiveGood will extend to European travel sites during 2010.
The system works by having a dedicated button within the booking path to allow users to make their $2 pledge.
