United Stripes organizes airline crew parties and other aviation related events. United Stripes was found by three airline pilots in 2009. It quickly became the most popular event amongst Dutch pilots and flight attendants. Part of the proceeds go to charity 'Luchtvaart Zonder Grenzen'. In 2011, United Stripes launched the United Stripes Cabin Crew Charity Calendar. All proceeds of this 60's pin up calendar went to 'Luchtvaart Zonder Grenzen'.
